UI-View is not unique in this area.  According to the eyechart at 
http://www.eskimo.com/~archer/aprs_capabilities.html, in the category 
"Provides local APRS server socket", APRS+SA, OziAPRS, UI-View, USA 
PhotoMaps, and xastir provide this capability.

APRSISCE/32 in development mode now also supports a downstream IS-Server 
port.  This port supports full APRS-IS filters and also forwards packets 
upstream provided that the downstream client supplies a valid APRS-IS 
password.  I need  to get the current capabilities sent out to Curt for 
an update.
