What I found useful is to have a fixed schedule for the actual talk, but 
keep the recording online for an extended time (say 24h). And require 
the presenters to be available in a break-out room for any questions for 
an extended time, too.
That way any participant can choose which time would suit him best to 
watch the presentation, _and_ being reasonably sure that he can fire up 
questions later on.

I'd side with Michal here; having something this year will be 
challenging, as quite some ppl (myself included) will be on holiday.
Rather move it to start of next year; mid-February would be a good time, 
giving enough room to organize etc.

Cheers,
