You should have about 1MBit/s, right. It works over ISDN (64Kbit/s even
better with doubling lines to 128Kbit/s) if your're patient. Implementing
a VNC client doesn't look very difficult. I'm right now trying this for
Squeak (www.squeak.org) after I downloaded the protocol specification.
I don't know about a server but they say the server has to do all the work.

If you think about a light weight X-like protocol here and don't want to
transport large bitmap graphics or movies, this is the better approach. Or
you may want to check out wiredX (www.jcraft.com I think) which is an
X-server written in 100% Java.
As I said I wrote a simple morphic-like framework in Java in another email
here. I did this to implemented a remote accessible Kansas like
environment in Java. It was just a proof of principle and the project was
sort-of canceled unless I find some better ways of synchronizing multiple
images but for this I implemented a RemoteCanvas which was connected via
TCP/IP to a GraphicsCanvas which did all the drawings on the client.

I'd be glad to discuss this further, yes.
