I was talking about Qt itself getting developed (by Trolltech / Qt Software) 
rather than development *with* Qt.  At least I think that was mostly Mr. 
Corsaire's concern (cf. Phil getting hit by a bus).

Actually, same concern can be expressed towards Detlev too, Eric4, while open 
source, the only interface to its development we have is here in the mailing 
lists; if something happens to Detlev, there's no public repository so it's 
not possible to continue where he left it, but one would have to go back to 
whatever the last release was.
