Well here is what the spec says wrt to mon_names:
"For maximum portability and interworking, it is recommended that=20
applications
and users define host names containing only the characters of the Portabl=
e
Filename Characters defined in ISO/IEC 9945-1:1990."

So doing some like would probably cause interopability issues with other
OSes....

Yes see your point, but is aliasing all that common in non-HA environment=
s?
The relatively simple  patch I'm proposing is a small step in the right=20
direction
which would make statd work correctly on multihome servers.
Should we strive to make statd more HA friendly, YES!  but I would
suggest one step at time.... Meaning we should propose this match to Neil
for inclusion in upstream and then build on it... imho...
