The director can create an install for any platform because it's not 
designed to install into itself. The UI is about updating itself and 
that limits the install to the current platform. There is no such thing 
as a multi-platform runnable so I doubt this will change.

What you need is an UI on top of the director (the pure p2 installer 
app). There are two apps for that (the equinox installer and the agent 
[1]) but I'm uncertain about the current support and quality. I think 
the installer is capable of creating a cross-platform install.
