On the other hand, the cost, the proprietary license, and the total
absence of portability are all deal-breakers.  If you're talking about
what I think you're talking about, anyway. ;-)

Implementing an analogue to mountable views on top of one of the new

implements (part of) the WebDAV spec; not sure about the others.
