Subject: Sharing User 0 Programs

I am passing on a question for someone else on campus
so I am a little sketchy on the details of this question.

They are running a Vector Graphics 5005 under CP/M 2.5. CP/M 2.5
was described as a vendor modified CP/M superset allowing several 
users in the MP/M style. The system has a 5 megabyte winchester.

They have found that to allow separate users working on distinct
applications, they must have each user login to a different
user area. Unfortunately, the 5 megabyte disk is marginal and
there is not enough room for separate copies of certain 
applications programs. I am told that CP/M will search User 0
for .com files after failing to find a match in another user
area, but this will not work for programs that use overlays.

Does anyone have a suggestion on how to patch CP/M to allow
the sharing of programs with overlays?
