>> x10tox11, while a nifty idea, is simple-minded with the protocol and slow.

Not so much anymore.  It has been 60% rewritten since r2 to (try) to
cooperate with window managers, do more optimal buffering and flushing,
and cache a great deal of information.  Many things work now that did
not work before, such as pikapix, xwd, xwud.  All things run faster.
The worst performance degredation I have seen on the current version is
30%.  In some cases there is none at all (mathscribe, a very slick
WYSIWYG algebra system does some plotting that starts appearing 6
seconds after the computing starts (T0) and finishes at 11 seconds
after T0.  Under the protocol converter, it starts appearing 10 seconds
after T0 but finishes at 11 seconds after T0).

Many of the simple-minded problems have been fixed, like handling all
uses of UnmapTransparent (I count 3); not getting upset when an x10
client does a GrabMouse on an unmapped window (illegal in X11); adding
delayed write to slow clients (like X11 has); ridgedly adhering to x10's
ability to paint text, propogating non-device events up the tree like
x10 does (x11 does not), etc, etc.

Ugly indeed.  If you wish, I can send you the newest version now (it
will also be available when R3 appears), to see if this helps.  I'd
dearly love to fix any remaining problems.
