Dear Mike and friends of the IAC:
Rarely a suggestion for a meeting finds such enthusiastic backing as the
idea of Alberto.
Let me add that such topic has also raised much interest in the
theoretical community recently and is catching up. Reporting on this in
the meeting will be most opportune.
Cheers
Eulogio
