You mean, I suppose, that you'll create a db on your server for the
user, and load schema / data into that? Then dump it out to the user
when they're ready to go, and drop the db on your end?
Seems pretty easily doable to me.

How much memory your db server has, how big the db will be, what kind
of load it will have, how the db is tuned, etc... I'd try it out
after building a simple test case db and see how the system behaves
with say 1, 2, 4, 10, 20 etc users. Get a feel for it.
I think a bit more information from you on exactly what you're
planning to do would help to determine an upper limit on how many
users you can handle.
