Uhm, maybe a restriction could exist... but I don't mind about it.

OTOH since this idea started from a community discussion would be better to leave this competition open only for the Maemo Community members (and newcomers), and not for Nokia employees etc etc.
Also for the prizes, if you win a sponsorship for the meego conference in Dublin and you are also a Nokia employee you'll get some conflicts, since (maybe) you could be already sponsored to join this conference by Nokia directly.
