OO features make this attractive for me. What I find less than
attractive is the fact that the client has to poll the server
all the time in order to remain updated.

e.g., your GDemo is nice, but it clocks to about 70 % CPU load on
a dual-opteron Win2K machine here.

I'd like to have my servers to be big and powerful but the clients
to be thin and cheap. Which means I'd rather not have to poll the
server from the client every x miliseconds.

What I have been longing to see is an OO database with some sort
of publish-subscribe (event-driven) mechanism whereby the client
tell the server which classes or objects it is interested in and
the server notifies the client only when any one of those classes
or objects changed.

Something along this metaphor would be great.

Any chance of that happening?

Cheers,
Adem
