Starting a diff program from an email?

Hello Tortoise Users,

I'm writing a daily report of Subversion activity. Instead of attaching
textual diffs, I want the report to include links that fire up a diff
program. The report is sent by email, and the links look like (I made this
up):

<a
href="diff:svn://server/repos/myproject/trunk/dir/file.txt?rev1=234&rev2=235">
/myproject/trunk/dir/file.txt
</a>

How can I start a program from a link inside of an email? I wrote a batch
(.cmd) script that does what I want next: parse the URL, get the file from
Subversion at rev1 and rev2 (using "svn cat"), start up the diff program to
look at both.

But I'm having a hard time bridging the gap between the link and this
script. It seems to me I should register a protocol handler for the "diff"
protocol, but I have no idea how to do this.

Any comments/pointers?
