I was holding off on dropping a new Windows wallet build until I could include the escrow manager.  If you want a build sooner let me know, I can do one with the I2P stuff.  The code is already up in github.

The issue with darksend is that there is a hardcoded collateral address in there, which I find a little scary.  I want to look at it and evaluate it before making that stuff visible in the UI again.

jase there are a couple of ways to achieve connection encryption like that.  We use something like that under the hood for the escrow orchestration and market infrastructure.
