I'm all for interoperability so no issues from me. can't guarantee it for 1.6.0 but happy to implement it. maybe even give user a choice (with an always use this option). let me think about it a bit but definitely on the to do list now.
additionally, i have toyed with the idea of allowing the Android app to hold keys, just trying to pace myself as there's lots I want to do (distributed signing for example) and I want to do it right.
