You bring up a good point.  I would say that from a legal perspective nothing communicated to or by 'Boussac' has any meaning.  Paymium could always just say 'Boussac at bitcointalk.org?  Never heard of the guy' if we are unfortunate enough to need to take this thing any distance.

I think that all communications should go through official channels starting at whatever can be obtained from the Paymium family of web sites and including any e-mail addresses which are referenced through official e-mails or snail-mails from them.

I am sorry to report that so far I have gotten no bites on my solicitation for the initial legal work associated with ensuring that police reports have been filed.  I think it is time to explore other more mainstream channels.  I would appreciated assistance from any user in France who may have the ability to help identify and evaluate potential legal assistance.

I have also set up the following:

  https://sites.google.com/a/tcilgl.com/paymium/

I would like to publish as much information obtained by the community as possible which may be helpful in our efforts.

I would also love it if someone else had a better idea or wished to take a management role in this effort.  I suck at management and hate it and have a lot of other things I would rather do, but I don't want to let this thing just die away.  Crooks believe (correctly) that they can shit all over the Bitcoin userbase and get away with it without a fight.  This is wrong and and bad for the ecosystem and it pisses me off and I feel some desire to see it change even if I have to put in some effort.
