i didn't submit a talk for 37c3 because there's a rule forbidding the promotion of commercial products (the german rules say "auch nicht verdeckt"), which i think is inevitable in our case. we make OSHW but we also sell it to be able to survive doing that.
edit: i just got a reply explaining how to register a workshop ("self organized session", list will be announced in the event blog) or a lightning talk (but there will be less space this year, so might not work out). thanks!
(even if one wanted to submit a talk now, it is not possible as the "frab" submission page is down)
@mntmn it must have gone down in the last ten minutes. I was just on it
