AFAIK, Event Helper was the only one that worked for Phase 1 (unless you're part of a university or corporation that'll provide coverage for you). No such luck this time. Last time, someone from Space Center Houston talked directly to The Event Helper to arrange something, then Nine Sigma emailed it out as an option (i.e. my post from Oct 30th)
I have attempted to contact all companies listed on the registration packet.
For now I've only received a response from theeventhelper.com:
I apologize, but unfortunately we cannot insure you unless you are in the US and performing actions at an event venue in the US. Unfortunately you are the second client that has been sent to us in the same situation.
Sigh, this requirement again. It made some sense when there was hardware involved, but for a purely software-based challenge? DARPA does not require insurance for software challenges, so it is not a government requirement. Perhaps we can ask NASA to revisit the need. The biggest risk here is carpal tunnel from too much coding :/
