Ah your talking WLS.  Does this only work when you use weblogic's 
drivers or does it work with any driver?  I suppose we could do the 
same thing.  Does WLS handle moving the driver classes to the client or 
does it assume you have all the classes you need on the client?

Assuming it has the permissions.... or does WLS serialize the username 
and password?

Not currently, but if you want it start by adding a JIRA "New Feature"

Not yet.  Currently an client can only see EJBs with Remote interfaces 
via JNDI.

N/A, but we may change the above so what do you suggest we do?
