krnlyng/liar has considered going down the chroot route again but it would still need modifications for each device for some things. So we kind of dismissed it.

If anyone has any ideas that takes into account getting hardware input for each device through Sailfish (not using the Sailfish/QT or whatever sensor api stuff Sailfish can use as that can't be accessed in Android, unless you find a way to do that), and all the other stuff involved and are actually willing to help develop it then we're open to it. Then it would be the case of installing Sailfish the same way as Ubuntu touch does it in order to save space, and not have essentially 3 OS's for one ROM.

One thing we've considered is extending apkenv but the work involved to make that run all kinds of android apps is A LOT
