@adbattacker I've forked this project under https://github.com/denzuko/p2p-adb to apply this any the other PR along with addressing a few of the other issues still open on the repo.

@kosborn Hope you don't mine me picking up the slack a bit? I'll submit a few PRs back to your repo once I've caught up on some of the back log if your wanting any changes pushed to mainline.
