Is iFolder really, really SECURE??

I have a client that needs to offer such functionalty to approx 200 users
and 30-40 partners
Problem is partners can change overtime and as can employees.

Any solution implemented needs to be secure - is it ??

Don't suppose Novell provides a TEST account so that users can
down load the client and test it on their PC....

are they brave enough to expose a server to all and sundry ??

Even a 10Mb 'test' account would be nice ie. something a potential client
can try for say 30 days.
I don't mean a single Test account.... ie. customer fill in a request,
Novell supply username / password.

We thought of it but as a humble user our ability to "Lock" down a server is
very limited
