Financial regulations have little do to with the Fed. They apply to transactions in money, not money itself. It doesn't matter whether the transactions are denominated in USD or Euros, and now apparently Bitcoin.

It's not meaningful to ask whether Bitcoin could become compliant. Bitcoin exchanges and processors could become compliant. This means having in place systems to detect money laundering, etc. it might be even easier in Bitcoin, given how much transaction state is stored in a distributed fashion forever.
