It is competitive in performance or faster than most C webservers, while being written entirely in Common Lisp.
It includes a simple blog application with instant comments (itself a fairly unique feature) and ATOM feeds, and an unfinished card game.

Evaluation, 20100901
A very brief assessment of all web frameworks listed in cliki was carried out in September 2010. This assessment comprised: check websites, download source if available, attempt to compile, review documentation.
The review found that teepeedee2 had at least one polished website - which has, so it says, survived a slashdotting. Quite a polished installer, too, written in Lisp. Unfortunately installation failed with 'package "MOP" not found'. This one merits further evaluation.
