Knowing what I do about Fog Creek (which includes no specific information on this particular question) I would very much doubt they would ever do that. The support costs for self hosting are just too high to justify the expense. Often these costs come in more than a support tech's time, as certain problems require code base changes to fix.

Do you have some sort of governmental regulation that keeps you from using hosted products?

Even secrecy-minded orgs like the CIA are moving apps to these platforms. Typically a regulation won't say "no cloud", but e.g. FISMA would require an online infrastructure to pass certain third-party assessments.
