Ah, that's cool!  That's cleaner than I thought it'd be, I thought it'd
be some kind of ugly hack.

It would be really awesome if you could edit the file and have the
object automatically updated.  That would be a lot harder.  I suppose
using the file alteration monitor stuff in GNU/Linux and Mac OS X, you
could efficiently get notification whether the file changed, but polling
might not be so bad.  I guess the hard part would be re-registering the
object with Pd.
