Let me keep playing evil's advocate.

Are you considering the fact that plenty of professionals will be paid to work full time developing MeeGo openly and this will give an advantage over those purely volunteering?

Until now this situation was an exception. Myself for instance, toping the ranking since always (something that didn't make me proud, actually). Imagine if we would start counting commits at http://maemo.gitorious.org and imagine that most platform nokians are there mmiting every day. Imagine that they really move their bugzilla actuvuty outside.

How will you address the fact that developers from companies have high chances of being the ones on top? Combine this with the fact that such individuals can move roles inside a company or van change companies overnight.
