On "what to do with service on acquisition", I've been thinking about that a lot -- basically as we set it up, we've got a plan to maintain service even if we moved on to something else, by charging enough to make the service self-sustaining from the start.

I'd make an acquisition contingent upon allowing the product to live on (either with the acquirer or an independent entity or a non profit); this doesn't impair our enterprise value much, since the product doesn't compete with any potential acquirer. I'm looking at putting this into contracts with customers. (a product could still eventually get sunset, but I think a year or two is a reasonable period post-EOL announcement, not a month...)
