Salve Sean, Oleg, *!

Sorry, it was not my intention to then my mail to the list,
and probably it has not the right style/sound - I didn't want
to write bad about globallocal, I just feared that assisted
data for the globallocal AGPS is based on a non open protocoll.

That I don't know enough, or that globallocal AGPS chips are only
talking with globallocal AGPS servers or just proxies, which are
talking with globallocal servers?
Or both? :)

This is fine, but i would like to run an own AGPS server,
connect via SSL to him and use the AGPS power of the chips
as well - without running fees beside the GPRS traffic
and without leaving information of my localisation on any
third party server.

Even more, when the assisted data protocoll is open and our
test with the Neo1973 shows that it worth to use AGPS, I like 
to lobby that a MediumWave Digital Radio Mondial station would 
broadcast LEO or AGPS data.

But Sean answered us and I will be polite and patient.
I'm conviced that the globallocal chip will be great,
but because of this great feature inside the Neo1973,
I'm a bit afraid that AGPS has no free protocoll to serve
AGPS data ourself.
