People who are being so super bullish despite the US Government telegraphing their intention to do something about Bitcoin should strongly consider protecting their stack. If shit really goes down, it will be a real $110 to $70 drop and you may never see the buying pressure return. Shit gets real at this point in BTC's evolution.
If they wanted to destroy Bitcoin, CampBX would be down. Dwolla payments to CampBX would be down. And MtGox's assets in Japan would also probably be frozen. Check out the previous cases of poker and Kim Dotcom. If they wanted to shut down MtGox, www.mtgox.com would look like this
Since they can shut the site down whenever they want (joys of being a .com), and they haven't, that's generally good news.
Crypto currencies are here to stay. The US Govt is better served by tracking the Bitcoin exchanges, instead of pushing them further off the radar. MtGox likely wasn't playing nice and ignored DHS, so they slapped them around a little. If MtGox gives them all the logs (transactions, ips, account info) they'd use it to track people on their watchlists and let MtGox exist. It's probably easier to track wires then Dwolla, so they're forcing people to use wires to deal with MtGox.
There's still a lot of unknown, but overall if it's just some KYC/AML requirement issues (re: letting the govt spy) its fairly minor.
