yes.

when it would be not so much data that is transmitted via GPRS,
because we select only the needed satellites and use a good
compression... I can image enough situation that this GPRS traffic
would worth it.

Network neutrality is no question for GPRS/SSL.
A dream would be, when the network poeretor wouldn't be just neutral,
when they serve assited GPS data for free or a fixed price (1-2
Euro/month)

When there is an open protocoll for serve assited data

It seems that SUPL (Secure User Plane Location) is for this,
HP has an own protcoll and did compared both here:

And an idea for an WAP extension:
Because some network operators have interesting tariffs with wap flat,
it could be work to serve LTO or AGPS data via wap to have fixed costs.
