If I weren't already running a company, I'd jump on this in a heartbeat. Spending a weekend working on people-matching algorithms sounds like a blast.

I'm guessing that the restriction on location is mainly related to keeping the travel costs down. I 'm mainly just curious as to why the US Citizenship is a hard requirement, particularly if I'm accepted to work on my own stuff.

This is pretty cool. Although I wonder what "grouper" is getting out of this. And why grouper is willing to part with good money. It seems wasteful to me.

Sounds like a great way to screen, invite, carry out an extended interview and potentially hire/acquihire selected targets. :)

Who owns the IP that may come out of this?

One of the items on the application form is "I am a US citizen". Is that a requirement for their Hackations?

Cool. Developer interaction always sounds good to me, so, signed myself up. Let's see what happens.

I added a clarification to the application that US citizenship is not required.
