A good friend of mine has been doing a fair amount of X programming at MIT and uses only X10 because he said X11 was too slow becuase of the byte/pixel reason. Perhaps he's wrong, perhaps the implementation he's using is brain-damaged even though the protocol itself isn't. Thanks for setting the record straight. (I guess that teaches me to try and write intelligent comments late at night. :-)
