Al Feiveson asked about NASA having Stata installed on more than 9 computers
when NASA has a 9-user (concurrent) network license.  Al explains

> Right now, we have three people who use it for most of each working day,
> about two others who use it maybe one-third to one-half of the time, one
> with about 10% usage and about 6 others who have it installed but rarely
> use it.

It is up to Al to determine that NASA is in compliance.  For Al's information,
StataCorp does not require that monitoring software be used.  We trust our
users and administrators to make reasonable judgments.  By Al's description,
the expected number of concurrent users is

      3*1 + 2*(1/2) + 1*(.1) + 6*.05 = 4.35 

Our license is not about average usage; it is about concurrent usage.
Nonetheless, the average can help to characterize the peak load issue.
Because of how Stata is installed on separate computers, Al cannot use 
software to limit usage to 9 persons.  Al must therefore make a judgment 
that he has sufficient licenses to cover all likely contingencies
and StataCorp will trust his that. 

Alan Neustadtl <> asked about licensing for 
student labs.  This is different than the standard, network, concurrent 
license that Al asked about.  These licenses are explicitly limited to 
education use in student lab networks and are priced accordingly, which is to
say, dirt cheap.  StataCorp does not provide software for monitoring lab 
use, but we do not prevent you from using such software as many labs do.

Alan wrote that he personally could not use the lab license (outside the 
lab) and was not covered by the GradPlan.  Evidently there has been some 
miscommunication.  All students and faculty at The U. of Maryland are covered
by the GradPlan there.  Alan can purchase on the GradPlan.  When StataCorp
receives any order from anyone known to be from the U. of Maryland, or from
any university or college participating the GradPlan, StataCorp fulfills the
order at GradPlan prices unless the order would be cheaper under standard
academic pricing.  That sometimes happens because upgrading a Stata 10 to
Stata 11 for a recent purchaser is cheaper at upgrade academic pricing than
purchasing a new copy on the GradPlan.

If anyone has questions, they should feel free to contact us, either
via email at or via telephone at 1-800-782-8272.  
We are not in the business of gotcha.  If you tell us about something 
you are doing that turns out to be in violation of our license, we will ask
that you address the problem in a timely manner, but we will not demand the
problem be fixed today and we will help you to find a solution agreeable to
all parties.
