What kind of remoting will be implemented ? some kind of home-made 
remoting protocol, HTTP, RMI ...? or something based on interfaces and 
plugin extension which would allow to provide different type of 
communication ?

That quite a big challenge. Just by thinking about it, I can imagine some 
"funny" things you will have to deal with : transaction and concurrency 
management, propagation of updates to client, lazy initialization, and so 
on ...

I'll be waiting for the first milestone then.

Thanks.
