[aprssig] -IS to RF Igating (was: APRS on Android)

I'm not familiar with all of the IGate software out there and can only 
speak for my own APRSISCE/32 which currently only supports gating 
messages for recently heard local stations from -IS to RF.  I do plan to 
implement filtered additional gating with both burst (per minute) and 
sustained (per 10 minutes) throttle limits   I'm even considering a 
per-callsign throttle limit per minute so as to limit those stations 
that mis-configure an APRS-IS-only application to beacon every 10 
seconds.  The filters will also hopefully allow selection of packet 
types that will be gated, but I haven't really gotten down to that 
detail in my design yet.  But no matter what I end up implementing, it 
would still be up to the IGate operator to specify the filter and adjust 
the limits as s/he sees fit.

Others will have to weigh in on what their preferred IGate software 
supports as far as additional -IS to RF IGate configurations and imits.

What callsign do you operate your iPhone under?  I checked aprs.fi for 
K9LGE and only found a digipeater last heard in July of 2010.
