That definition of source and destination is pretty much what they
give in the Accelar documentation, but to be honest it doesn't make
much sense to me.  In any case, current releases of the Accelar system
software (which our stuff is based on top of it) do not appear to
support global filters, as you saw in that boot message.

Yep.

I didn't get much luck using source filters either.  My current
version of JFwd uses destination filters (modulo a bug that RobJ found
today).

The JFwd stuff seems to more or less get through my (pretty minimal)
in house tests.  The JCapture stuff is stalled for the time being, I'm
afraid.

What versions of everything are using?  I ought to be roll a more up
to date version of the everything next week, I think.  We're moving
from one building to another over the next couple of days, which means
that everything, including our test lab, gets pretty disrupted.
