So, if you thought the last post was short. Try this on for size! Ages ago I found Wolfgang's Vault, a repository for a buttload of classic concert recordings, posters and so on.
For those of you lucky enough to have an iPhone, search for "Concert Vault" in the App Store. It's only bloody streaming Wolfgang's Vault! Plus, you don't need WiFi. The App senses your current data speed and adjusts the bitrate of the stream accordingly.
I've tried it in a really dodgy 3G area and it worked perfectly. It's also a really nicely designed program. Don't believe me? Check it out here.
