[FOSDEM] Submitting to *both* devroom and lightning talks track allowed?

Dear FOSDEM-organizers, we would like to apply for presenting a new project at FOSDEM which would fit both as a "general" lightning talk and also partly in the "testing and automation" devroom (our project is about testing, but not so much about automation). We are unsure, whether we are allowed to (1) submit only one lightning talk (having to decide for either the lightning talk track or the devroom) (2) submit a lightning talk to both tracks (3) submit a lightning talk to the general track and a specialized 30-40 min talk to the devroom We could not find any regulations concerning this and, thus, would like to ask which of the above options is allowed. Many thanks in advance. Cheers, Daniel
