I've been organising with some of the OSM folks to do a demo of OSM and related
tech at Linux.Conf.Au happening later this month in melbourne.

I was wondering if the OSM map download stuff is in a release version of gpsdrive?

Also if there is interest we can do a BoF or similar.

Please contact me if theres any other things you'd like demo'd or announced...

regards,

Kim
