It was no that much money in fact, and I am sure some student with a bit of time could do something really cool here. We were pitching the idea to build an address book for the iPhone that could read foaf files, and that would do what I had written some time ago in Java, (but with a much better User Interface for sure) namely

Dead cool. I may just buy an Android phone just for this!

We need to talk more on getting deeper WebID implementations for this. Can you make it tomorrow for the WebID XG weekly meeting?

(let me know off list)

Excellent, news. I think this will be very interesting to all on this list..... 

I'll get a phone and investigate this...
