[Xastir] (no subject)

[Curt, WE7U]

Latest stats.  Xastir is keeping up with APRS+SA fairly well up to
at least a couple of million packets.  It looks like it is only a
matter of time before Xastir will be the #3 most popular APRS
client, instead of #4.  The key percentages here are in the last
column.  It shows the percentage of callsigns+SSID's that are using
each version.

The longer I run the script, the more Windows machines show up.
Does that say something about which OS'es/APRS Clients are more or
less stable?  I don't know.  UI-View has been climbing, and gets
near 74% when I run my collection script for multiple days, so they
have 3/4's of the users.  WinAPRS has been dropping in the
standings, the longer the script runs, the lower they go.

I've been thinking that it might be interesting to do a graph of the
usage over time, taking a snapshot every XX time period or every YY
packets, so that the working set of APRS clients can be compared
long-term.  I haven't gotten around to doing that yet though, but
it'd be nice to have on a web page somewhere.
