  You can run non-graphics applications from any supported terminal
  and the list of supported terminals is growing

  Yes, but you have to consider the potential resources you are 
  going  to tie up.

  This is not a smart move!!!  Native Xenix applications will run
  faster, more consistent, and be much less impact on the overal
  system, and  require much less resources!!

  Performance for 8-10 users will be poor.  You need a minimum of 2mb
  per user for large applications.  1mb per user is a dead minimum, plus
  2 mb of general resources for VP/ix.  So for 10 users, you are looking
  at 2 + 10*1  = 12mb of ram.   And you will be eating up many many 
  cpu cycles!!!   VP/ix is NOT a multiuser DOS environment, but rather
  an environment to run your few DOS applications that will never
  be ported to Xenix.  (IMHO)

Hope this helps.
