So I answered my own question. Or at least the second half. I would still be interested in learning if anyone else has actually packaged this application up for the zaurus, but in the meantime I have cross-compiled it for my Z. It works very nice, espeically the web server version from Opera.
The attached archive contains the arm compiled binaries of tide and xttpd, and a shell wrapper for both called xtide. In addition to those binaries, you will need to download the harmonics file
and make sure you have the zlib and png libraries. Following the trick from another thread, you can create a symbolic link to libqte for the png library:
ln -s /home/Qtopia/lib/libqte.so.2.3.2 /usr/lib/libpng.so.3
XTide is was written and Copyright by David Flater. I created the xtide shell wrapper, but all other portions of this app are not my work.
