We first had the idea of a select set of beta-testers which then would be given a free license for their testing work. However, that idea has the disadvantage that we won't get a lot of feedback on the design of what we create for v2.0. So we're likely to open it up for all our customers, so the beta will then be usable with the current license and time limited, and the full version will then work with a new license.
Expect beta to start in Q1 2006.
