It wouldn't be hard to prototype a coin mixer using the raw transactions API and a centralized web service (accessible via Tor, if you're worried about it recording your IP address). @p{par}

If you want to do a really good job, though, you'll need: @p{brk}
  + Lots of people participating and/or @p{brk}
  + Lots of time so your mixes are spread out over time @p{par}

The 'lots of people' will take time, because the mixing code needs very high trust since it'll be spending your coins. @p{par}

The 'lots of time' might be a practical problem, because the mixer needs your wallet to be unlocked so it can sign mixing transactions. @p{par}

Somebody should create a working prototype and then for a Bitcoin Foundation grant to fund the web service for a year... @p{brk}
