I'd be interested to see some examples of Bitcoin contracts used right now.

  • Websites that provide escrow services.
  • Smart properties.
  • Trading of contracts.
  • Oracles.

Or are they not really in use right now?

  • There's a system of distributed oracles that launched last month - oracles.li , with a whitepaper available here: github.com/orisi/wiki/wiki/Orisi-White-Paper . Right now the test oracles allow for timelocking bitcoins, and there are other transaction / contract types coming soon, hopefully.
