OK, so it's likely that everything will just continue to work
remotely, and people won't experience any problems.  And they won't
have to run VNC just to get their favourite app to display remotely.

If this had been explained clearly to begin with, we could have
avoided all this pain.

It looked like a bunch of kiddies who had never used remote X
applications had decided we didn't need to do that anymore, and it was
more important to get kewl features like smooth scrolling and rotating
3D whatnots.  It seems that isn't true, and we don't need to worry.
The lunatics have not, in fact, taken over the asylum.

Andrew.
