I for one would be very interested. However, I'm with Guylhem when he suggested that there are "too many distros on Zaurus", in the sense that if all the effort making cacko, pdaX, pocketworkstation, angstrom, oesf, openbsd etc were put into one version we'd have something more powerful.
Snag is that each person developing for the Zaurus do it for their own interest/satisfaction and thus have widely different goals.
I started to write a humorous summary of each distro's motives but I think it might have been insulting to everyone!
