Ahh, okay.

well, a quick discussion later, and it looks likely that we will build a
xAP
hub into the xPLHal engine. It already includes an xPL Hub, and as xPLHal
runs as a windows service, and it is likely to simply cause problems if the
xAP hub may or may not be present, it probably makes sense for it to be
embedded.

In essence, the machine with xplhal on it will have automatic xAP and xPL
Hub facilities.

Okay, that helps. I think we have enough to get building. Tony and John
have
split the work between them, and expect to make quick progress.

Sure did :)
