[aprssig] Cross-Band Digi or Gate?

Greetings,

I'm working on more advanced capabilities for my APRSISCE/32 APRS client 
software and am wondering what the proper approach is for gating (or is 
it digipeating?) HF traffic onto local VHF frequencies?  Is this an ok 
thing to do, or just gate the received packets to APRS-IS and be done 
with it?

If I do cross-band them, do they go out over VHF with just used callsign 
insertion into the path as a digipeat or does it go back out as a 
third-party packet?

Are there any good (read: current) guidance on paths for HF APRS?

I guess what I'm asking is just what did the old dual-ported TNCs do 
when configured with GATE?  I'm guessing that software gates can/should 
do the same?

PS.  Yes, I have been following the 10m APRS discussion on UI-View and 
read Bob's HF.TXT file (http://www.aprs.org/APRS-docs/HF.TXT) last 
updated in Jan 2000.
