  for the most part, yes.  However, there will be a few things that are
  boarder-line as to wether they are SysV or BSD.

  Only with the greatest of pain.

  Actually IBM (as always) has their own flavor of administration tools
  called SMIT (System Management Integrated Tool).  To be perfectly
  honest, we have had to use ALL three flavors of Admin tools to get
  the job done...

  Again, for the most part, yes.  Some of our developers have found a
  few of the BSD library subroutine missing, though.  Actually this AIX
  tents to be more SysV-ish than BSD-ish.

  These all work fine, however, there is an annoying management tool for
  system daemons called the SRC (System Resource Controller) master, which
  is supposed to proved a common control mechanise for deamons.  But it
  is inconsistent in that certain daemons will not respond to it, and
  (worse of all) it looses track of them and can't communicate with them
  again! (note: this is a bug for which there is an update comming any
  day now...so they tell me).

  Don't know about that...don't have any diskless stations, only 320s
  and a 530...oh and a bunch of X-stations (120s)

  Haven't seen one, bit there is one for X11R3.  One thing to note: their
  implementation of X11 on their 320s and the X11 that runs on their X-stations
  do *not* act the same way.  Example:  We just had a demo of FramMaker2.1
  for the RS/6000.  The demo (called demomaker) would talk to the X-station
  without any problems at all (nice graphics too), however, when talking to
  the X11 server running on the 320, it kills X!!  I mean the X process
  dies!  (Interesting, you say?...)

  Yes, it's their prefered flavor.

  Haven't found any holes yet (yes, I've looked for them).  IBM tried to
  close up as many holes as possible with this version of AIX (after all, they
  planned to sell these things to the likes of the Government).  However,
  their "golden" copy of the OS that is being shipped, even as we type,
  has bugs in it.  We come across them almost daily.  But, fear not, for IBM
  has an Update in the works that is supposed to fix them Real Soon.

  Of the hardware we have (530,320s,120s,13" color, 19" mono) only one of
  the 19" monos' had to be replaced.  In the beginning of the installation
  process we turned all of the machinery on/off several times a day, and
  haven't had any problems.  Oh, I jsut remembered, we also have a 4019
  LaserPrinter, which had to be "rebuilt"...IBM prefered to rebuild it
  instead of replacing it, because the paper work was less (do they claim).
  The One thing I like about IBM is that their hardware is very stable.

>    Any other comments?
  Software, on the other hand.....well, there's a lot to be desired. I
  know they meant well, but IBM did what IBM always does when they enter
  into a market, they imposed their own standards on Unix.

  Looking back at my comments, it occurs to me that I was a bit cynical
  in my responses.  AIX v3.0 is an addequate implementation of Unix,
  however, integrating their system into a network of other systems
  will not be trivial.  While I'm not trying to turn you off to the RS/6000
  (really, I'm not), You should ask VERY detailed questions of IBM before
  you buy.

I'll let others with more BSD experience answer many of your questions;
I'll stick with ones with more straight-forward answers.  

In general, porting things from the net (say from comp.sources.unix)
is pretty straightforward.  A good number of things port in an
hour or less...my personal time limit for most mildly-interesting things.
BUT ... the trick described in some documentation with the BSD environment
variable doesn't seem to work at this point.  There's an excellent writeup
on porting code from BSD to AIX 3 that's supplied in /usr/lpp/bos on the
distributed system.

These have MX, MB, MR and MG support.

We've had good luck with these (I haven't used YP (sorry, NIS) extensively).

No.

Not at this time.

Yes.

named is BIND 4.8.1, sendmail is essentially 5.61 with a few enhancements
like National Language Support.  It supports MX *and* MB, MG, and MR records
(as far as I know, it's the first commercial sendmail to do so).

All of AIX tcp/ip, from the kernel to the applications, is pretty much
straight BSD-tahoe (NFS and YP are straight Sun).  There's been support
added to the daemons to use the System Resource Controller, which lets you
start, stop, and refresh daemons remotely, etc., but you can use them the
normal way (start from the command line, use kill to refresh/stop).  If you
choose not to use SRC, just comment-out its /etc/inittab entry, and the
/etc/rc.tcpip script will start the daemons normally--no muss, no fuss.
