I'm toying with the idea of creating a solidcoin to USD exchange (and perhaps support for other forks), but obviously there would be quite a bit of work involved so I'm wondering if there is strong interest in this?  I'm thinking of allowing deposits directly by ACH, I've discovered that ACH transfers are not reversible after 5 days so I could implement something reasonable with that, and I can allow credit card deposits with about a 3% fee (there would be some verification involved initially), and wire transfers.  Also Coinhunter any bounty on this, didn't see one for USD exchange.
