>From a coverage perspective, it's very pleasant to have the two sorts of
nested X server, one that's a protocol repeater and one that's a
software rasteriser.  However, we have two protocol repeaters: Xnest,
and Xdmx.  Ideally what I'd like to see is Xnest implemented as an Xdmx
personality; you should be able to just symlink the one to the other and
have it act like the Xnest of old.

>From a non-coverage perspective, the Xephyr approach to nesting does not
scale.  Xdmx had a xephyrish mode once, and it just doesn't perform well
beyond a very small number of displays.  There are any number of reasons
for this - lack of compressed image transport for example - but it does
indicate that both approaches could be worth keeping for reasons of user
experience as well as pure test coverage.

But in the long term, yes, kdrive needs to go away.
