don't know about XBee, but the open source firmware for SiLabs Si1000
SoC radios has improved a lot recently.
https://github.com/tridge/SiK
HopeRF makes a 433 MHz Si1000-based module, there are probably others too.
We've been getting good results with prototypes of the 900MHz HopeRF
module (8km range @ legal EIRP limit, using 1/4 wave dipole and
external amplifier). I'll be testing some 433 MHs ones in few weeks
and hope/expect that even without an amplifier or directional antennas
they will be a cheap, practical, long range link (low bandwidth) link.
For paparazzi, with this firmware, don't forget to set MAVLINK=0
(ATS6=0; AT&W), so it's just a transparent serial link, otherwise it
will try to insert radio-status MavLink messages and pack data into
MavLink-specific frames.
