Meterbridge uses lots of large bitmap blits to draws meters, so ssh is
going to eat all your cpu in crypting up the bitmaps to send them over
ethernet.

You could try ysing a cheaper cypto algorithm (eg. blowfish), or better, not
tunneling over ssh.

If you have hardware GL on the X client machine you could wait for the GL
version of meterbridge - that would just have to send the GL instructions
over ethernet which should be much more practical.

I think trying to tunnel fast moving X apps over ssh is... optimistic.
