Sam, I think it's a good concept, but what about security? I have seen books and articles on privacy urging people not to link their real names, addresses, and phone numbers on the Internet?I don't know the answer, but it's something to think about.
On the other hand, I think it's time for people who love traditional music to start doing their own publicizing. The traditional information sources (newspapers, radio, tourist bureaus) are so prejudiced against trad that it's swimming upstream to get any co-operation from them.
