Read through the FF startup scripts, it is in there. X gives us this
amazing capability (network transparency) and the Mozilla team went out of
their way to prevent it working for Firefox apparently to prevent someone
accidentally starting firefox on the wrong box. Bizarre. They have been
doing this for years.
It seems you can now set en environment variable to tell FF to act
rationally:
MOZ_NO_REMOTE=1

In 15 years I've only come across 2 apps that didn't allow for remote
display under X:
1) A game ported from Mac OS-8 or OS-9. Whoever ported it didn't
understand how X was supposed to work and forced the use of shared memory.
2) tvtime, a TV app. The developer is on record as saying he can't see
why anyone would want to display it remotely. I discovered this while
trying to display it remotely. Go figure :) xawtv and friends work just
fine remotely.

You could channel bond gigE cards for a fraction of the price. Maybe
worth doing this to see if everything works the way you want. Then when
you are sure it does you can lay out the cash for the 10GE.

10GE won't kill wireless any more than wireless would kill wired LANs
(another often heard claim). Each has advantages over the other. I
predict more of the same: most ppl will stick with WiFi as it is easy and
cheap, while a few will roll out cables in their home.

You can cut-n-paste between X apps connected to the same X-server
regardless of whether they are local or remote. I do it every day.
I highly recommend the use of ssh-agent. This will make your access to
all your boxes transparent and allow you to start X apps remotely just as
easily as locally (no password or passphrase to enter). This is how I run
my systems and I've been known to occassionally forget which box was
actually running a given app.
