Last I know they said about 1 or 2 meg per user, so it sounds like dedicating 1Gb of ram for users isn't a bad idea. But if ram is "cheap", always over-specify. Dunno about AIX, but linux will grab spare ram as disk cache and that speeds things up as well. AIX should do the same.
Long ago in the dim and distant past :-) we ran a 32-user PI-Open system on 16 megs of ram. It wasn't a pretty sight :-( with the disk thrashing like mad. But it was still a pretty fast and responsive system! Upgrading to 32 megs still made quite a difference, though. So that gig over and above what AIX and other uses requires should give you a pretty nippy little system.
