Any capability to fill non-browser OS dialog boxes? In the product roadmap?

I have previously used a competitor to 1Password that had one feature I will miss. That solution could not only handle form filling within a web browser but could also fill dialog boxes that would appear within the Windows OS that were spawned by other applications. For instance, I use the Cisco VPN client for access to my work systems and this solution would fill the UserName and Password for that tool when it was presented. FYI, this tool, which started on Windows and only recently made the jump to Mac, could only do this on Windows systems.

Any plans to add this feature to the inestimable 1Password? If so, any insight on whether this would be available on Windows, on Mac, or both?
