What I've been saying for ages is that the biggest problems for the open data movement are mostly found inside Government agencies. Until the open data promoters can establish a cohesive pitch, based around solving goals for the agency in question, then these technical solutions are a waste of time. Nat's latest 'open source' model for open data will only excite those already sold on the idea.
Most of the people who need convincing as to why they should get on board the open data train, need to be sold on the benefits to *them*, not the benefits to the technical community.
Yes, but with PSTN integration you can use your standard Telecom phone number and direct it to your computer or VOIP-enabled device. On an iPhone for instance, you would be able to receive phonecalls through a standard phone number, at local calling costs (ie, free) anywhere in the world.
For some strange reason, the telcos don't want to enable such a service.
