The current implementation of Live Text uses a proprietary protocol and server to get the text into the Flash widgets for the radio network sites. An open protocol would be better, but will XMPP scale to at least 100,000 concurrent clients?

Hopefully they will also implement either botbouncer.com or their own CAPTCHA service otherwise there will be tears.

So if you are a VC funder or a journalist and some project is being sold to you as a Semantic Web project, ask how it gets extra re-use of data, by people who would not normally have access to it, or in ways for which it was not originally designed.
