RSSI value questions

[Ryan Crawford Comeaux]

I'm looking to build an application through Google's Summer of Code for the
school server that uses wireless location detection methods to monitor and
approximate the physical location of all nodes within the mesh.
Unfortunately, I can't seem to find any information on whether or not the
network allows the server to poll nodes within the network for RSSI
measurements the nodes have made between themselves and all others within
their range.

Is this something that the networking firmware/drivers even allow?  If not,
is it functionality that could be requested of Marvell to provide?  If so,
how accurate are the RSSI measurements and to what decimal precision are
they available?

Also, what kind of interest within the community is there for this kind of
application, if any?  I think the idea at least has interesting uses as far
as securing the network goes, but I'd really like to know what everyone
actively using and/or developing for the systems thinks.
