R:link and hosting multiple sites off a single radiant insta

After reading the suggestion at
http://dev.radiantcms.org/radiant/wiki/HowToHostMultipleWebsites

I tried setting up just such a system. It largely works; however,
unsurprisingly the r:link tag is thoroughly confused. As radiant does
not know that apache is “rehoming” all of its tags, I get goofed up
links.

If I am missing something and there is an easy way around this
problem, please let me know. If not one thing that is working for me
is this simple patch against r:link, allowing for a “base” option that
is removed from the front of the url.

Thanks for Radiant
