Android versions without DRM? Since smartphones have become "the thing", it has somehow been decided that locking your phone to a particular primary e-mail address and having DRM is "okay".  Android, despite being open-source, is somehow not the exception.

Since Android IS open-source however, it would seem that a developer would be able to customize it to remove the primary-email restriction on the phone and to unlock all purchased applications to be available to whomever is using the phone at the time, only requiring a sign-in to purchase new applications or when using certain applications.

I don't currently use Android, and bought a Windows 7 Phone only to find that it does the exact same thing as Android (and most other phone operating systems)  Are there any Android projects that are attempting to move Android towards a DRM-less environment?
Paid Apps are tied to an Google account. But this is because of the Google Framework and not because of Android. No one needs to "remove DRM from Android" because there is no DRM within Android. Only support for it. If you install free (as in beer) Apps, everyone can use them.

There is only one imitative that goes one step further then being DRM-less: Android FOSS Apps @ http://f-droid.org/
