Ask HN: Invite manager?

Hey all-

So today, I was setting up a beta invite program, and I thought to myself "what a pain in the ass this is." The next steps I realized are also pains, get the right people using them, collect bugs, get proper feedback etc. So then I thought SWEET, uber successful startup $$$$ here I come. And then I looked around, and found launchset, which looks pretty sucky. So what do you guys think? Viable product, micro isv, or just a lark.

Thanks.
