I think this is a really interesting point, because I don't think FLOSS is quite the answer, either. If you just want a dependable service that's going to stay around, and you're willing to pay for it, what do you do? As you say, anything that is SaaS could be canned/sold/etc. Anything that's FLOSS won't be as much of a service as you wanted, presuming you wanted to pay money on an ongoing basis to have a problem solved in a convenient way.
