The Canadian subsidiary of XM is selling the music/audio element but
still just making promises about XM weather "RSN" (real soon now.)
The US website for XM weather now offers a range of packages for
boating; the top one specifically includes "high resolution Canadian
NEXRAD" -- so XM has access ot the Canadian radar data; they just
haven't gotten organized to sell subscriptions to that data to
Canadians.

The US XM site has online subscription forms; these only accept US
billing addresses and will not take a credit card number issued by a
Canadian bank.

Don't count on XM doing anything new until after the merger takes place.
