Excellent.  Let me know if anything wonky happens.

The "app" directory should now be called "examples".  To get it to show up
automatically, you have to enable the DEPLOY_EXAMPLES option during the
cmake phase.  But don't worry about that too much if you've got a working
setup going already.

Fantastic.  The dependencies on ws4py and autobahn were the trouble I
referred to earlier, but I'm glad to hear they were easy to install (I
couldn't remember how much was involved in getting those two packages
installed).  I'm planning to make these dependencies optional so that this
isn't such a snag.

Very cool.  Please let me know if you run into further issues.  Happy
hacking!
