I only see support for Chrome Apps and Extensions in the
docs, so the web version is unlikely to help here. There are no official plugins for Cordova, although mobile web will be getting some more attention now that we've gotten iOS and Android out the door.
I do see that Ionic has some cross-platform plugins already, like
this one. If that doesn't help, I think a community supported plugin will be the way to go for now. Ping me if you run into technical questions. Glad to help, and I'll bet I could find an engineer or two to answer my questions if we can't sort it out : )
