No, I was simply elaborating what Michael was suggesting.  However, if
your frontends are dynamically assigned using DHCP, using static addresses
defined in the database or hosts file is not a tenable solution.  The
easiest option will probably be to put static assignments into your dhcp
config, and then define those addresses in your DNS server.  Or, you can
have each machine statically choose its own address and a host file.

The ideal solution would be for mythbackend to track connected frontends,
and which ones are running a control socket.  Then add a command that
MythWeb can poll to find available machines to connect to.  As it stands,
MythWeb simply attempts connection to all frontends with a port listed in
the database, and waits for a timeout.  Personally, I don't think this
system is worth trying to improve upon, rather than outright replacement.

That's not really a MythTV problem.  The MythTV source installs all
binaries on all systems.  It does not support a frontend-only installation
with no mythtv-setup.
