I think WFS(-T) was a kind of suggestion.

Yes, if particular application needs to identify a device, then it could
be solved by application-specific identifier system,
with some help on the protocol side.
For example, user/application is configured to authorize with remote
service using ie. e-mail address + password, transmitted by a WFS-like

Yes, but first simple solution could be implemented and tested, then we
can see if it's enough or not.
I mean, there are many Web services like YouTube, Yahoo!, Google, etc.
every service provides it's own authorization system, based on HTTP(S)
protocol. Similarly, every provider of remote service for GPS users
should has a liberty for implementing its own authorization system.

I can't and I don't think it's needed.
I just discussed what is available and what is not, in this matter.
