Two of my open-source projects, Alpaca and Hansa2, are hosted at Sourceforge.
Another, Clotho, is hosted at common-lisp.net.
I like common-lisp.net better so far.
Alpaca and Hansa2 are both written in Common Lisp.
Alpaca is a Mac OS X (Aqua) application written in OpenMCL. It's an extensible word processor for prose authors, supporting rich text and WYSIWIG page layout. At the same time, it's an extensible Lisp environment with Emacs-style extensible key-bindings and a Common Lisp API. Alpaca has a Lisp listener.
Hansa2 is an implementation of the trade game Hansa, invented by the economist David D. Friedman. The game is generally similar to games like Empire and Risk: the goal is to dominate the world. The great difference from other games is that in Hansa you expand, not by conquering your neighbors, but by persuading them to voluntarily join trade leagues, by making better offers than competing leagues. Hansa is also written in Common Lisp, and consists of a portable server and N platform-specific client applications (where N presently equals 1: there is an OS X client, but Windows and Linux clients are planned).
Would common-lisp.net like to host these projects? If so, I'd be interested in moving them over from Sourceforge.
