I wish the best to VersionPress, but this will likely kill a lot of their potential integrations and relationships. The bigger WP players who would want to support something like VP would have been web hosts, but now they've become competition.

I feel like a paid (remote?) version of their software would have made a lot more sense, ala CodeGuard or WP StageCoach.

We emailed them several times trying to gain access to their private staging beta with no luck. There seems to be too much focus on impressing developers rather than reaching out to potential partners in the web hosting world...
