That would explain the design and lack of server functionality. Not your
fault. What I mean't was that if someone came along and said u should do a
server portion, u could tell him to go somewhere else as your intention
would be (i) no such functionality, (ii) a small binary and (iii) a lower
limit on max nbr of records. U could also skimp on the transactions bit,
table locking and row locking.

Agreed. Conceptually RMIJDBC is doing what a server enhanced InstandDB would
be doing - sitting there in memory and waiting on a socket/port for a
request. But I seriously wonder if it can handle the table/record locking
with multiple requests(queueing?). I believe it would be READ-ONLY mode
right? Truthfully, I haven't asked or investigated in dept.

Come to think abt it, You could cpy the HypersonicSQL server portion and
have a basic server running pretty fast. Maybe if I had the time I would try
it but then I discovered you're not open source..oh why oh why....ANy plans?

I will investigate. But when i went to the site...it screamed alpha so I
went away.
