Looking for telemetry transmission hardware, I came across following offer made by Digi (ex-MaxStream):
XBee-PRO 868 OEM Development Kit w/ 2 XBee-PRO modules

Apparently, the kit is available for a promotional price of only 99 USD until end of February 2009.
The package contains following:
(1) XBee-PRO 868 w/ RPSMA Connector
(1) XBee-PRO 868 w/ Wire Whip antenna
(1) RS-232 Development Boards
(1) USB Development Board
(1) RS-232 serial Cable
(1) USB Cable
(1) 868 MHz RPSMA Antenna
(1) Power Adapter
(1) 9V Battery & Clip
Various Adapters
This 868 MHz short range device has software selectable transmission power (1 mW (0 dBm) to 315 mW (+25 dBm)).
RF data rate is 24 Kbps (10% of duty cycle).
Incredible Outdoor/RF Line-of-Sight Range up to 25 miles (40 km) with
dipole antenna.
Serial data rate of 1.2 Kbps to 230.4 Kbps.
It needs 3.0 – 3.6 VDC power supply and transmitter burns 500 mA typical at 3.3V (800 mA max), receiver only 65 mA typical.
Apparently, for the moment it is ETSI approved for Europe (without special license), but no FCC approval yet for the US.
I think of it as a must have... Can't wait for the Swiss reseller to send me my quote to confirm my order.
