I fully support this request!
to be more specific:
forward the position reports to the APRS-IS-network (Tier2) using POSITION + COMMENT

so that http:\\aprs.fi or other APRS mapping websites or client software will show call, symbol, position and comment text on map.

the benefit would also be to combine position reports that are given by different means e.g. different radio technologies or frequencies ( D-Star, APRS, Winlink, Winmor, PSKmail)
into one single track of the ship or 4x4 mobile.
please do it!
