I feel your pain :-) As the coordinator of the Perl user group I know
from experience that the lightning talks meetings are very popular but
very hard to organise. It takes as much effort to get one person signed
up for a 5 minute talk as it does for a 30 minute talk so trying to fill
a schedule with 12 minute talks is a huge job for the organiser.
But if you do it, I'll be there!
Cheers
Grant
