Just a quick thought. If you really wanted the master to IR blast for
the slave then you could setup the channel change script for the slave
to simply be an ssh /telnet call to the master, which then calls the
actual channel change script. It's reliability and responsiveness
could be questioned, but assuming it's a wired ethernet connection
between the two then I think the call would be reliable. The only draw
back is that it might be a few extra seconds to change channels.
Just an idea...
