Hi
Short answer : no. It's not possible to integrate them "out-of-the-box".
Long answer : YES. It's possible, but you will have to modify some files. It should be very difficult, but MySQL & PHP knowledge are required.
We planned to give login support for google accounts, facebook connect, openId,... so we could with wordpress also. It's a great idea, we already have a roadmap for 1.1 version, but we could put that on 1.2 roadmap.
Thanks!!
