RaccoonOnMap, a Google Maps mashup with mobile (web servers), is now supporting both variants of mobile web servers we have here: Raccoon and MWS (aka Mobile Web Server).
Easy instructions of how to setup the MWS (and Raccoon) to use RaccoonOnMap can be found here:
Those people using the phone's internal GPS device need to run MWS 1.1 or later. These versions have signed access to location capabilities of the phone. These capabilities only allow to use GPS device, not cell id information, which means that location the user without GPS signal is not possible to get.
