BTW, if you just want to be able to send/receive SMS's in a Python application, there are several alternatives. 1. Most operators, or 3rd party bulk-SMS vendors (who resell SMS capacity from operators at a premium but in smaller bundles than what an operator would sell), offer -- a. HTTP based mechanism to send/receive messages b. SMPP protocol. OpenSMPP has a C API, and you could create Python wrappers for same.
2. For very low volume application, you could use the Serial (or Serial emulation over USB/Bluetooth) way, i.e. using "AT" commandset of a tethered GSM mobile (with inbuilt GSM modem), or a separate GSM-modem (PCMCIA, USB,...) via Python, to send / receive SMS's.
