Sure, but SVN already has the DCT6200 firewire channel changer built
into the code, so an external changer isn't required.  Why would I want
to change that, other that to add a call to "firewire-tester -B -n $node"?

Note that it would be even more fragile to do this because the channel
change script wouldn't handle node changes, unless Myth could pass
the nodeID to the script, or at least could pass the STB GUID so that
one can parse the output of plugreport to figure out which node the STB has.

Admittedly it would be best if we never had to reset the bus at all, but
in the face of HAVING to reset the bus, I'd rather myth did it (or had
hooks to do it externally in a good way) rather than having to create
an external channel changer that would reduce the functionality of
what Myth currently has internally.
