Hi all,

It seems that time is to short in order to organize
a useful meeting; those people who contacted me are
mostly available at incompatible dates, or non expert
as to the brainstorming sessions.

I therefore decided to cancel the meeting this time.
We just finished a new proposal today. In case of acceptance,
we should have money for organizing another one later,
and we will be able to foresee longer in advance.

Best wishes, Joris
