How do I distribute Android app to beta tester without using Market

I have an early version of my app that I want some testers to take a look at. But I am not ready to put it on Market. How do I distribute it to my testers and how do they install it on their phones. One of the beta testers has a Asus eeePC with Android 2.0 installed and I would like him to try it too. How does this work?

How do I distribute Android apps for testing?

Distribute your app to testersOn the Releases page, select the app you want to distribute from the drop-down menu. Drag your app's APK file to the console to upload it. When the upload completes, specify the tester groups and individual testers you want to receive the build. Then, add release notes for the build.

They can just download it from any URL (go to the URL using the device browser) and install it.

They'll need to go to Settings->Applications and check the "Unknown Sources" checkbox.
