Thanks!  I have finally added 1b to the firewall manpage.  I chose to
not include 1a.  I also extended (and documented in the man page) the
RSYNC_CONNECT_PROG environment variable.  It now supports a %H escape
for the hostname that allows the hostname from the rsync command to
affect the command that is run.  Cool stuff!
