Re. wireless networks that know where you are without making that info available to anyone incl. net operators: I think I might have something for this. Ericsson wireless PBX; essentially similar to a cellular system. However, calls within the network are considered "intercom" calls and so the system's "call detail recorder" won't keep track of them. Ericsson is way hot in wireless voice and data networks; and we're their local distributor for PBX products. I haven't got prices on hand since we haven't gotten a request for something like this yet. However, if anyone's seriously interested, drop a line via email or phone me at 510-644.8085. -george gleason, gg@well.sf.ca.us
