I too would like to know the answer to this, both from a realistic standpoint (I think you can open more than one database, if you start another session of Sesame), and also from the "legal" standpoint.  By that I mean, can I "legally" open up a second session of a single installed copy of Sesame on a standalone computer and be accessing two different applications at the same time?

I have something in mind that I would like to be able to do.  If I build a "utility" application in Sesame that provides information that I can use in other Sesame applications, I would like to be able to open that utility application and have another Sesame application running at the same time.  I can then generate the information in the utility appl. and copy/paste it to the other application.  I don't want to have to insert the "utility" appl. inside every other Sesame application that I might create.  I think this would be too much effort and overhead, unless someone can argue otherwise.

Comments and discussion on this from the Lanticans, and everyone else would be most welcome!
