yes. Everyone can participate in it (no user limits or something - completely open). Open beta will be approximatly one week before the real launch. The open beta clients will be technically the same as the real clients on launch day (with a little modification, so it will use a testnet that coexists further on).
when does the first round of investing end? im under the impression that the 22 is the last day but i just want to make sure.
also one of the claims that you make is that the code is brand new built from the ground up. so one of the stipulations for releasing the funds that i am holding in escrow must be that you prove that fact. any ideas how to handle this catch 22 since you say that you need the escrow funds released before release but that the code will be closed source until release?
