Hi, I don't know if anyone has posted on this product yet, but I learned about a project on Kickstarter that is trying to create an adaptor that allows you to use your trekking poles as 2 out of 3 legs for a tripod. The third leg is just staked out line, or you can use a 3rd hiking pole if a buddy has one. Brian Green put out the word yesterday on his blog; that's where I learned of it.
I want one! it's exactly the solution that I've been looking for. I've backed his campaign, but he needs a lot more before February 14th to make it happen. It seems like a no-brainer for ultralight folks that like to take pictures: small, compact, uses equipment you may already carry, and proposes to be pretty light-weight.
Check it out and if you like it, back it! you'll get your own polepod when they go into production.
