This is really interesting. I have been having conversations with a bunch of folks in the Portland area about trying to find funding with a very similar model.
Glad to hear that other folks are thinking, and doing things, along these lines.
I love the fact that it is offered as a line of equity. Being able to get money when you need it, but not take it if you don't, makes it a lot easier to keep your spending low, and not have a pile of cash burning a whole in your pocket.
