You're (licensing) reasons for wanting to manage this are also good and
right (and legally required).  I support what Crosswire is doing and is
trying to do completely.  That said, whatever you decided to do with
respect to (re)distribution rights will be honoured, but it needs to be
clearly communicated.  If modules are not to be redistributed, impose that
constraint and be transparent about it.

All of my 'more current' modules, and other works I'm working on are in a
separate private repo that does not permit anonymous access.  What goes
into my public repo are only those things I purposefully intend to share
(primarily with you folks). With respect to modules in the mirror copied
from CrossWire, you can check - they are exactly the same as at Crosswire.

When a change happens at Crosswire, my mirror detects and duplicate (only)
the changed modules (just like an rsync).  If a module does not change,
nothing happens (thus the only BW consumed is when a change occurs).  You
have asked me not to redistribute modules with
"DistributionLicense=Copyrighted; Permission to distribute granted to
CrossWire".  So when the filesystem (on my end) changes, i.e. a file is
copied over, the filesystem (using lsyncd) checks the contents of the file
for DistributionLicense and prevents access to the ones you don't wish be
redistributed. In a sense my mirror is a perfect mirror though it doesn't
share those modules you don't want me to share.

I don't see the problem.  As mentioned linux distro mirrors do this all the
time.  That is why tools such as rsync and lsyncd have been created.

Simply and clearly.

I wouldn't mind working through some of the Beta module issues as
previously mentioned, so I may just head over to the wiki.
In faith.
