If you're still up for this, publish the source on GitHub. That's an excellent idea and I'd like to participate :)
@dane-pgp's suggestion of verifying the hack by checking the source repository is great too. Maybe it'd be easiest to just name the endpoints something like `/ping/github/<handle>/<package>`.
Awesome! Thanks, a ton! I haven't touched it in a while but I'll take a look at it now. I'm going to take a stab at fixing it up a bit and then I'll put it on my (currently empty!) github. I'm a bit leery of including my username in an HN comment - I once made the mistake of mentioning my twitter handle here and got some weird selfies in my DMs - so I'll put my github username in my HN profile for a day so you'll know where to look.
