I find these rather useful, most of them comply with what we are 
using here now.

In Europe many countries use special callsigns for fixed stations
like digipeaters (like OHmRnn in Finland, DB0xyz in Germany, SRmnnn
in Poland), so we are using -0 for most digipeaters and igates.

D-STAR does not have an SSID system as such. There is a 8-character
field for the callsign, and the varieties of gateway software seem 
to translate callsigns like 'OH3BK  M' to OH3BK-M when it is delivered 
to APRS-IS. This leaves -5 for handheld APRS over UMTS devices, as 
I'm using both those and D-PRS regularly.
