Is it possible to run a complete Gnome desktop from a remote
 location through ssh? I'm not talking about using vnc to watch a
 remote desktop but actually run one remotely and only have it
 displayed here.

 SSH also includes functionality to allow X11 forwarding through the
 encrypted SSH connection.
 
 You'll need a fast (100mbps+) lan for it, even with the ssh compression
 enabled.

I've not done it and don't know the details of the protocol, so can't 
really argue from the practical end, but if it requires that, how'd they 
ever do it back in the day, before XFree86, let alone xorg?  Back then, 
10Mbps Ethernet would have been fast, 2 Mbps would have been standard, 
let alone dialup.  Sure, screen sizes were smaller back then, but that 
much?

BTW, from what I've read, it's generally 2D and possibly unaccelerated 3D 
only.  Accelerated 3D generally makes use of DRI or other direct 
rendering client to hardware, not over the socket, so not over the net.  
As I said, tho, I've no first hand experience, so I'm just going by what 
I've read.  It's also possible that AIGLX (Accelerated Indirect GLX), a 
relatively new development, might have changed that.  If so and that's 
what you were talking about, yeah, I can imagine /that/ might take some 
bandwidth.

OK, so I see the answer... single apps with smaller windows, not the 
entire desktop run remotely.  And Conway's point about compression 
sometimes slowing things down if the CPUs are slow compared to the 
network makes sense as well.  CPU speeds (and now cores) have increased 
faster than network speeds, I believe, tho I've not done the math on 
actual years.  The network may well have been fast enough for the CPUs, 
back then.
