The xServer takes incoming TCP connections - mainly to tunnel xAP
across the internet between two sites.  The clients are basically
minimalistic but have a profile key which is administered on the
server to determine which way traffic can flow and for which devices.
This allows clients to have controlled access (server administered) to
specific devices.

My adapation just allows the client to augment any existing filter
restrictions. Thus for say a Crestron or AMX implementation - that is
interested in modelling only one particular devices it reduces traffic
to only relevant messages. Alternatively it could set up a class
filter (or both). This maximises speed on the embedded processors and
removes traffic the processor can't handle.  Targeted messages can
still traverse the router.

Yes - it's just a little awkward for some schema where the last xAP
message isn't necessarily a status one...
