Mount Directory

I posted this suggestion on Sourceforge, but I thought I'd reproduce it here for discussion purposes:

I would love to be able to "mount" a netowrk drive location on the URL path. For example, I have a network drive called "Server1" containing documents I would like to link to in my wiki. It would be nice if I could add a line in the config file such as "mount : Server1" and then in my wiki pages, I could link to documents as by "img:Server1/First%20directory/CoolImage.jpg". Then, when the server receives the URL, it will identify "Server1" from the config file and find the file on the network drive.

The issue here is that people accessing the wiki from within the network can directly access documents from the server using a URL such as img:file://Server1/First%20directory/CoolImage.jpg" *IF* they are using Internet Explorer. Other browsers such as Opera and Firefox will not display the image or link to the "local" file (if it is a .pdf or just a directory listing, for example). I don't know why that is -- I have attempted to find out, but can't get any information on it. If I copy the link and paste it in the address window, then it works, but it will not link from the wiki page.
