[Koha] Serving an Intranet WebPAC from a Website

Dear Koha Community I have a Koha site that intends to publish their mature WebPAC to the globe. However, they decline to assign a public IP and DN. Their preferred route is to serve KOHA pages via their website hosted on Windows/IIS. Koha is on Ubuntu/Apache2 webserver. I had thought of using samba to share the Koha opac DocumentRoot, then create a virtualhost equivalent on IIS. Before I labour on this, any Koha geeks out there who can advise if this will technically work? Thank you Regards /Bravismore
