Likely.  But I'd ask why.

First:  X is a network-transparent system, meaning you can run an
application, or your entire session, over the net.  

That said, there are some good reasons for keeping at least bits of your
X session local.  In particular, the window manager.  Mostly for
performance reasons.

Even over a high speed network, you're going to have both latency and
bandwidth effects.  And even if your _net_ latency is low, and bandwidth
is high, periodic network "burps", etc., can gum up the works.

My recommendation:  run a locally managed X session.  Run the remote
apps you must run via an ssh tunnel, launching them from a remote shell
with an appropriate DISPLAY value.

If you *must* run a remotely managed session, look into ssh compression
and lbxproxy (the low-bandwidth X proxy).  They'll help somewhat.

And note that there are environments which translate better to remote X
than others.  Particularly twm, fvwm, blackbox, fluxbox, and xfce.  My
own preference, WindowMaker, generates a heck of a lot of network
traffic (mostly dock apps).  It's a pig over DSL, and, well, when I
tried it over a 56K dialup, it worked....after about 15 minutes

I'd strongly discourage use of GNOME or KDE over a remote connection.
VNC will do you better here.
