I would love to buy this but the anonymity is a big problem for me and a lot of others.
So I propose this:
The team can remain anonymous, but they find an escrow whom they trust and is known to the wider community. That escrow releases funds to them as they hit milestones on the roadmap. There's no reason they'd have to reveal themselves even to the escrow, as long as he is trustworthy.
Any reason this wouldn't work?
I'm not sure why their anonymity is a problem. We give our money to shops without faces all the time. This team has a product; they are raising money to develop their existing product. What does it matter if you can't see them. They could easily hire people to 'be' their face, this is done all the time; but instead they chose to build a product and let you decide if it benefits them. They are trying to help *you* with a product they already have in existence, not something that doesn't exist. If you like the product, pay for it, if you don't...don't pay for it.
This said an escrow is not a bad idea perse; even my team which wants to be anonymous for our protection had to come up with ways to ensure that no one person on the team would run off with the money or that there would be checks in place to ensure that funds were used as they are intended to be used -- as agreed upon by everyone before participating. Even 'known' faces have this issue.
I have no problem buying their product with their anonymity. It's buying the crowdsale that has me pausing. Because that part of the product won't be delivered when I pay them. That part is promised to be delivered in the future.
