This will be interesting to see. I'm relying partly on the idea that there's a fair degree of trust, and expectation of support, associated with Saxonica's reputation, and that the people who are risking their business on the product might be hesitant to rely on third parties, who won't necessarily be prompt in issuing maintenance releases etc; at the same time, such third parties may serve the needs of the hobbyists who are the real market for the open source version.
