OziExplorer is the package that i use the most, it's a really qick windows application and has lots of maps redially available. I've tried it under wine but for some reason it slows down quite drastically but you can still talk to the gps w/ it. If gpsdrive could support the map formats from Ozi easily that would be a good solution and if there was a native linux verison of OziExplorer that would be even better
As an amateur radio operator or ham. I have run accross some troubles you can have w/ a voice activated cicruit (vox). Most amateur radios and commercial ones to have a ptt (push to talk) button on them but occasionally some people forget the other aspect which i refer to as rtl (release to listen). Since most radios are simplex or 1/2 duplex you need to unkey the radio to hear the other person (and/or make sure they haven't switched frequencies and left).:)
A trouble w/ a vox circuit in that implimentation will really show up in a mobile environment. if you go past a construction site you will find that instead of the conversation you were listening to, you are now transmitting all the noises arround you.
On a duplex conversation, like a phone, it is always transmitting and recieving at the same time. This has an advantage of you can interupt the other person but there's a tendancy to not pay attention to the other's conversation as the tendancy is to ramble on more instead of shorter messages w/ a pause between.
Additionally for a situation as above like driving by construction some people will forget that they may not be able to be heard over the noise. the natral reaction to that is to talk louder so you can be heard but that only makes things worse. Radios and cellphones have really sensitive micropones these days and talking louder will only distort what you are trying to say.
Digitally encoding a voice for radio communication has been done and is being done by hams, it's not all that new. It is quite possible to send somtihng like that by 802.11 even using existing technologies. Record the voice to a digital format (ie.wav file) compress it for efficient space (ie.mp3) stream the file to the other machine with oh say shoutcast/icecast. Building something like that into a pda like the Ipaq/Journada or a Palm. While a project like that would be a bit much to build for just a normal conversation the geek factor is quite good.

Sending a signal up to a satellite is fairly easy and somthing that ham radio operators have been doing for years. AMSAT is a good place to check out what has already been done as far as getting a signal up to an orbiting target go. Additionally some ham radio operators have opperated at what's called moonbounce or EME (earth-moon-earth) where they send a signal off the moon and back just for a bit of a challenge and the fun of it. There is also information arround on high power transmitters that are used for that. Hams have been able to do that sort of thing for years. Keep in mind though since that information is public others can do the very same thing. Also somone with a malicious intent won't likely be concerned with government communication regulations.

if these universities are being tapped how can they be secure??? :)

Looks like although quality is job 1, Security is job 3.74rc3 :)
Seriously though a big company has more to worry about from people you thought were employees than from any computer system breach.

Indeed, i have to agree with you there.
i'd almost say that linux is toro to be too specific.
