[mh] How to send OSD annoucements to multiple mythtv frontends?

[Chris B. <ch...@ba...>]

I have a couple of MythTV frontends in my house and would like to be able to
send OSD announcements to all of them in one go.  As far as I can tell,
code/common/mythtv_osd.pl will only support a single "myth_notify_address".
Does anyone know how to do this?
