Joel is heavily involved in StackOverflow.com and the whole StackExchange universe, so it's likely he has a good handle on support costs for hosted products. Fog Creek also offers a hosted version of FogBugz (free, I think, to students and open source developers) so that's more experience in support costs and issues.
