Is it possible to use HAM radio for net connections? there seems to be plenty of things in the Linux kernel for it.
Yes. Some people are running 10mb duplex links to the net. However, the large bandwidth requires the use of microwave frequencies say 10GHz and the equipment is usually homebrew. I will look up a site on the web with construction details if anybody is interested!! There is also an extensive packet radio network on which tcp/ip can be run but speeds in the uk at least are very slow, although useable for radio purposes.

oh I forgot to mention all of the red tape and the need to pass a City and Guilds exam to gain a licence!
