GSM location service

I'm working on a GSM location service that can detect the current
location based on the GSM cell towers seen by the phone. we are
currently in a fairly early stage but there is some proof of concept
that seems to be useful.
I would like to discuss the way we can integrate it later as a proper
The interface all applications use is the Gypsy interface of which a
subset we can provide with the GSM data (there are no satellites
obviously). But currently frameworkd is implementing this interface and
I don't know if an interface for me to connect to frameworkd and say "I
am a new location service, get data from me if you don't have GPS data"
or something like that.
In fact, I'd like to have a low level GPS service that the GSM service
can use as well since part of it is collecting data to find the cell
towers which are later used to generate the user location even when GPS
is not available.
It should also be possible for the user to configure which services
should be active, a user may want to enable just the GSM location
service, disable all or enable all and take the best information when
available so that if he is outside the GPS will give him the most
accurate fix and when he is inside a building the GSM will continue to
give him this data (with reduced accuracy).
Is there a plan for this already? If we can sketch a plan for this I'm
willing to code it up.
