I've been looking into autodiscovery and came across this message and
one from about a year ago (during the SoC project) also associated
with a closed ticket (due to the SoC project mfd work... which was
never completed TTBOMK, that ticket can be seen:
http://svn.mythtv.org/trac/ticket/750 ). I realize I'm showing my
naive side, but I'm not that familiar with UPnP yet. Does this patch
make it so a frontend can basically just "work" as in (for example):
Lets say I have a backend running with this patch applied and I throw
a knoppmyth CD (for asumption lets assume it's running the same SVN
revision...) with this patch applied. After bootup can I just start
using my frontend? Or is there still a requirement to use a keyboard
(or SSH) connected to the frontend to perform some setup?
