Indexing citations and quotations…

Ok, here’s a call to someone that knows PHP (since I know only enough to be dangerous…)
I stumbled across a really cool MT hack, and was wondering if this would be easy to do for WP? Since I’ve installed the Super Uber Blockquotes hack (which works great), it seems like this is the next logical step. Check out this page for citations, and this page for quotations.
The actual MT templates that power with can be found here.
In a nutshell, these scripts/templates are scouring posts and indexing cite tags (for citations), and q and blockquote tags (for quotations.) It’s giving a list of either people or websites with the number of references, like this:

Quotations
The following is a list of websites that we’ve quoted on Our Story.
* diveintomark.org (6)
* oblivio.com (3)
* theooze.com (3)
* daringfireball.net (3)
…

Then, when you click on one of the items (for example, diveintomark.org), you get a list of each post where the quote (or citation) occured:

Quotations
diveintomark.org
These entries quote diveintomark.org.
