Some folks up North are using 802.11b 6-7 miles at 6~7 Mbit.

The WA4DSY modem will do 56 kbps (http://www.paccomm.com). It operates at 29 MHz and must be used with a transverter for the appropriate band. Some hams in Slovenia have designed high speed equipment, see http://hamradio.si/hid.html for some links.
