In all seriousness: Isn't it fairly unrespectful towards Vimacs to somehow imply that enough boot-licking will have him "come back"? I mean, I can see both Craigs and Vimacs side on this matter - Vimacs not comfortable with working together with EvilCraig (that is, the Craig that appears in times when he really shouldn't post), and Craig realizing that a quite nice part of the OS code actually was not under the control of the project. I quite understand Craigs reaction (which was, as far as I get, actually fairly civil - He noted that they might not be able to use the PND code and offered to handle Vimacs wish to cancel his order). I quite understand Vimacs frustration.
However, that is what it is - A disagreement between Craig and Vimacs. The problem for Vimacs is not that he hasn't gotten enough ego-stroking from loads of forum members - The problem for Vimacs is the attitude of Craig. The problem for Craig is not that he hasn't heard loads of forum members proclaim their love for Vimacs - The problem for Craig is that he realised Vimacs owned parts of code that could possibly be leveraged to substantially hinder OS development at the whim of Vimacs. Never mind if that would happen or not, this is at this moment a huge problem businesswise (a lot bigger than whether someone might or might not be honest with a warranty claim in some unspecified future).
Vimacs has done his part here in as good a way as he could whilst keeping self-respect - He has (literally) laid down his weapon by signing over the code to someone else, thus making sure that he is not any more a possible threat (bear with me: From the view of this conflict, that is, not that I claim that he ever was or would be). That means Vimacs has disarmed (or at least moved to Skeezix) Craigs leg of the disagreement. Now, the move on the other leg is Craigs (or somebody else at OPs) - There would need to be a re-establishment of trust between Vimacs and the project, somehow either convincing Vimacs that Craig will be able to keep EvilCraig under control, or that EvilCraig is not a problem in the great scheme of things. If this is to succeed, I'd imagine personal contact is appropriate, possibly apologies or explanations, possibly drinking of beers, slapping of backs and tellings of anecdotes.
However, a chorus of forumites going "Ooohh, Vimacs, come back" will not settle Vimacs disagreements with Craig. To imagine that it would is to imagine, somehow, that Vimacs staged a tantrum to get som fan attention, and I don't really see that in Vimacs.
