There was 'something' mentioned on the GS forums ages ago...
GS were working with Garmin, and the two 'fell out' when Garmin started their own listing site.
(Or was it, Garmin started their own listing site when things weren't all tickety-boo with Wherigo?
)
Ranger Fox seems to be working on things, but without financial input, and a decent hand from GS (who have copyright/trademarks/intellectual rights etc) isn't going too quick.
