There is crossplatform VNC. I've heard that its protocol is much more
network friendly than one of X.

What do you mean with "network friendly"? That I have to buy a
higher-bandwidth network connection for more money from my network
provider?

I'm not entirely sure what the OP meant, but VNC by default compresses
its traffic, so it reqires less bandwidth.

AFAIK VNC transfers screen contents all the time, so it requires very
much more bandwidth than X. Compression helps a little, but does not
make up for the basic inefficiency. I have heard that they have put
optimizations in for more efficient transfer, but also that these
optimizations are based on something similar to the way X transfers
its graphics commands.

Yes, you can get X traffic
compressed as well, but it doesn't happen by default.

I also would not want the machines on our LAN to waste their CPU
cycles with compressing and uncompressing X traffic to save bandwidth on
a network that has enough bandwidth.

And when I'm doing X across the internet, I use X over ssh, which
allows me to use compression if I need it.

IMO, VNC's nicest feature is its stateless display. I can use it on one
machine, close it, and go to another machine and pick up exactly where I
left off.

That's certainly nice, but I doubt that the OP meant that with
"network-friendly".
