[aprssig] Tiny Tracker?

This is the sort of thing I brought up last week... wouldn't it be nice
if the first digi in the line was smart enough to figure out that this
guy had sent the same position over and over and over, and auto-bud list
him?  Well, not exactly budlist... rather filter his packets.  After
all, sending the same position over and over will always yeild the same
checksum on the packet and the standard dupe checker could filter him,
but it'd catch any repeating message packets too. 

What would be ideal would be to have a digi that was smart enough to
filter out redundant position reports from the same station if sent more
than once every 10 minutes, but yet allow retries on message packets? 
Such a digipeater would be more inline with a "switch" than a repeater.
