	MDS and AutoDoubler will only decompress APPLICATIONS into RAM - MDS
because most documents are data based not resource based (which is how MDS
accomplishes it's "to memory" tricks) and AD because documents are opened 
read/write which implies to them to decompress to disk (since that means it
can be modified).

with applications that "play games".

	First, let me clarify this comment.  MDS, AD & SS when they compress
files do so in such a way that the icon on the desktop is still the same as
when it was decompressed.  Only DiskDoubler visually changes the icon.  However,
AD & SS actually change the type & creator of a compressed file, but "fool"
the Mac into seeing the original info.

	No, depending on who you talk to, the fact that MDS does NOT change
this information is a distinct MINUS!  The reason that SpaceSaver (and I would 
assume AutoDoubler) changes the file's type & creator is to protect the user
from working with files on non-MDS equipped machines.  For example, if you
take an MDS compressed MSWord file to a Mac w/o MDS - the file is still 
an MSWord file, but the data inside is NOT!  This can lead to some VERY BAD
situations.

	Based on information posted in the Alysis support area on AOL, MDS 2.0
has been released and is required to use with 7.1.  There is an upgrade cost,
but I do not know what it is.  AutoDoubler 1.x is also incompatible with 
System 7.1 (in some ways), and a paid upgrade to 2.0 is required.  Only
StuffIt SpaceSaver does NOT require an update for 7.1 compatibilty - works
right out the box (sounds like pretty good compatibility to me ;).
