We are struggling with this issue in our College.  Our IT people
reported that Stata Corp. does not license a network version or allow
regulating usage through a network.  This means that we are purchasing
multiple licenses (with a discount) to have a legal version of Stata
on lab each computer.  However, the IT folks do not believe that the
discount license program applies to faculty office and home computers.
 Practically, the lab licenses are less than half the cost of a
license for me (not covered by the grad plan).

Given our current budget situation this is leading the College to
question Stata Corps licensing policy and look for alternatives.
Personally I would like to keep Stata for me and my students.

>> One way would be to assume some distribution of user entry and exit times and then calculate the probability that more than 9 people would be using Stata at the same time. Then if this probability is greater than some threshold, increase the license capacity. Of course if this probability is anything greater than zero, Stata might not like that, but then the only way to absolutely guarantee no more than N simultaneous users is to restrict Stata to N machines. Clearly we don't do that.
