That last bit sounds right - I definitely did not do anything on
special case terms - it's all or nothing with xFx. I think it was more
down to my implementation than anything else. Maybe James has a
clearer memory of this. I wasn't doing anything out-of-spec as I
recall, just tuning the way it was implemented as I think there were
duplicate messages arriving for each HS application on the same port.

I'm sure it was specifically when there were multiple registrations on
the one port. If you only registered a single client on that port
internally in your Hub implementation, it worked fine (as with
Patrick's as I recall??) but if you managed each individual client
separately as I was doing, they'd all receive multiple copies.

If that's how it was perhaps a note needs adding to the spec on this
one?
