Speaking at Identity 2.0 Mashup event

I'll be sitting on the panel for the Identity 2.0 Mashup event at the BT Centre in London on the evening of April 24th. The theme is "my digital identity is an asset but who owns it?" I have a feeling we will be unpacking the concept of ownership (if not necessarily those of identity and digital identity) in our attempts to come up with some interesting answers to that question. If you're in London on the 24th, why not come along and pitch in your insights?
