RAP will provide a JFace analogon, and JFace itslef provides lazy
loading for trees and tables. But as of now there is no ready-to-use
implementation.
For the trees You could easily implement lazy loading yourself. Just
place a dummy node as a child for each 'lazy' node and replace it with
the actual nodes when expanded.

Looks like that there is a limit. RAP does not put a limit, but if any
browser cannot cope with the load, then that will be the limit.
I will forward this to the qooxdoo - the JavaScript library RAP uses
client side - newsgroup, maybe they have some insight.
IMHO presenting 10,000 rows to the end user isn't a good choice anyway.
Imagine that after waiting that long as it takes to transfer all the
data You are overwhelmed with such pile of information.

In general yes, but I have no idea if it *really* works. You could
obfuscate the demo and see what happens to get some insight into this.
