If it's a classified system then you may want to think twice about
MoMA.  Although it is anonymous, MoMA does send information back to
Novell about your app.

In terms of updates, I'll have to find out about that as well. Unfortunately, around here it seems like we just continue using the original version of software until we have some sort of problem that we believe could be corrected by an update to the software - and we may in fact need to put in another request for that update.
