Nothing concrete that I can share at this point, except to say that it's being worked on. Android 4.0 has now added an official API that allows developers to plug-in a VPN client. We're exploring just what this API gives us and trying to ensure that it lets us build the same capabilities as the VIA client we just released for Apple iOS. There is also likely to be a VIA client for Android 2.x, but it would require a rooted device - unfortunately that's a limitation of the operating system in 2.x.
We'll have more to say as the plans become more firm.
