Paul, we've also been considering trying the byte code binder but heard
there were limitations.   However, I'm looking for some documentation
regarding those restrictions.  I.e. what can't I do with the binder that I
can do with the JVM.  Or is it easier to specify when I CAN do??  Can you
help point me to some doc on the subject??

Thanks,
-Darrell.
