It is not Eric Seidel's module (his CVS is still empty, BTW...).
subuni posted this on Slashdot concerning the Apple Rendezvous module for Apache, and I'm adding it here for completion:
Quickly looking at /usr/libexec/httpd/mod_rendezvous_apple.so, looks like it has the three following options:
RegisterDefaultSite Optionally, specify a port or keyword main; defaults to 80 RegisterUserSite Specify a user name or the keyword all-users, optionally followed by a port or keyword main; default is 80 RegisterResource Specify a path and a name under which to register, optionally followed by a port or keyword main; default is 80
Keep an eye on the Darwin Server Page for the source code for mod_rendezvous_apple.
