Hmm. Hackerspaces.org has been running global livestreamed hackathons monthly for over a year now:

http://hackerspaces.org/wiki/Synchronous_Hackathon

Indeed it will be the same weekend as your event... not to discourage you or anything. Lets see what you've got!

After reading more into it, it seems that they are targeting co-working type spaces, not individuals in their hackathon efforts. Yes there are synchronous live online hackathons but the niche difference here is definitely individual hackers.

(not necessarily contradicting you beardicus as I'm sure you were well aware of this, just first time I read it I was like: ohh, already done)

[SingAlong]

We are looking to bring together hackers, where-ever they are. Not just the ones who have a hackerspace nearby.

Didn't see this one before. It's a bit unfortunate but no showstopper. Stay tuned!
