Yes, I do not want the beacons or spots, but if anyone does send
a "message" directed to a particular callsign then that
"message" could be copied over to the APRS-IS for possible
delivery to that call if he is there.

I think I see the problem. There is no easy way to distinguish
between a spot, where the comments are directed to everyone,
from a spot, that is comments directed to the DX station...
Though some of the above examples do fall into either
OK, there are two processes...
1) Formatting an APRS message to send INTO the DX cluster
system. This should be easy and a very light load. Something
like sending an APRS message to DX and having the first word of
the message be the CALLSIGN. An APRS==>DXCLUSTER engine
somewhere looks for these APRS messages and injects them into
the DX Cluster system
2) Letting a DX cluser user send a message out to APRS is
another matter. Could it be as simple as one of the above SPOTS
having "APRS" in the callsign field? Then, again, the first
WORD in the spot is the intended recepient. This lets someone
who happens to be on the DX Cluster but suddenly has an urgent
need to send a message to an APRS user who is out driving around
in his car, to send that message as is where is...
