Here is some random stuff.
I have various bits of lisp junk in this darcs repository. There's my macro environment-let which is basically a framework for writing certain kinds of code-walkers. Also a nice little macro with-emit for generating a list efficiently by pushing stuff onto the end.Here is a patch that gives gaim latex support just like in Adium / Equation Service.
Here is a patch for ssh that does SNK (aka TIS authserv) authentication automatically (instead of asking the user for a response).
I wrote a patch for mutt that corrects some annoying behavior in the key selection menu.
