	I see it, it's a cool idea because then the IPC is immediately 
window-oriented.... more intuitive to the user, no?  One could then construct
'standard' commands to cut-paste text and IFF, etc... without having to go
through the bother of the clipboard.

	Hmm... the problem is that DOS has to be fixed first.  Asynchronous
incomming messages simply do not work on pr_MsgPort because DOS expects the
reply to its synchronous packet to be the next packet that comes back on
the port, which is stupid since a WaitMsg() call is just as easy to write
as a WaitIO() is for IO.  Right now DOS simply does a WaitPort() and GetMsg().
BTW, I have a WaitMsg() call in my new DRES.LIBRARY which is being released
soon (now being uploaded from my Amiga so the moderator can FTP it).

	-) It's kind of fun to be able to log in to my UNIX acct from home,
start a 2MB transfer (via DNET) and have it crunch on it while I'm at class.

	I wish it were possible, but alas.

	Actually, I think it would be better to EXTEND the window structure
in 1.4 and add another port, as well as fix the way IDCMP ports work now 
so one can share them more easily.
