"I have been testing the alpha release of Ubuntu 8.10 (Intrepid
Ibex), and one of the big changes in it is improved support for
GPRS/UMTS/HSPA cards. It looks like they are trying to make it as
easy as they have already done with WiFi networking. Assuming that
succeeds, you can then have a really portable video calling system
- no more running around looking for an adequate WiFi hotspot."
