Reducing X11 pointer motion traffic

Hi. I am testing a configuration where I can run an X app remotely by
using ssh's X11 forwarding. I've noticed that moving a mouse pointer
triggers many pointer motion events. This traffic goes over a
relatively slow network connection, so it tends to bog down the user
interface. Is there a way to reduce the amount of X11 mouse motion
traffic going across the wire? I've looked at lbxproxy but it runs on
the "wrong" end of the connection for my purposes.

Would VNC work better?

Before anyone asks: this pointer motion traffic is not an issue with
most X apps, so you normally won't notice it. But I'm using a
Java/AWT/Swing app, and Java has its own oddball behavior.

Chris

I thought I'd follow up on my post by saying that lbxproxy actually did
solve my problem. While it cannot prevent pointer motion events from being
sent over the wire, it can prevent many of them from reaching the app (the X
client), thus greatly reducing a lot of the subsequent back-and-forth
traffic that each such event caused. I used lbxproxy's "-motion" switch to
restrict pointer motion traffic.
