Ask HN: Android developers, would you use a website to beta test your apps?

Hey all, I've been working on a website that will allow app developers to upload beta versions of their applications and either allow the public to test them or a set group of users. I'm also developing a framework that developers can easily add to their betas to license it (only allow users who are allowed to test it within the beta period), gather usage information and report crashes during the beta period.

My question to you guys is would you find a use for this sort of thing and if so, what would you like it to be able to do?
