I know that a liaison was sent from MPEG to the W3C early may 2009 and that the WG was informed.

Actually, I had made a web page that describes it and that I wanted to send earlier [1]. You will find there some background information and the current spec in PDF and soon some examples and code. If you have questions about the GPAC implementation of MPEG-U, you can ask me but if you have questions about the MPEG process, you can post them on the general MPEG Systems mailing list[2].

I don't think that all that's listed there would be of interest to WebApps (e.g. I'd be surprised if the WG cared about integration with BIFS or ISOFF packaging, assuming members even have heard of them), but some topics (inter-widget communication, context management, aggregation) certainly are.
