it not practical?
I'm just curious... but I know the egomanics like Eyeore are going to

in with "Your a moron" bs to feed there ego's but luckily I have learned

What I mean by this is that I have never seen any mention of something like
this(although I think I do recall a 1-wire protocol somewhere but don't
remember much). I do know that you can encode a clock with data(I think its
manchester encoding?) but wonder why not move to the next "logical" step and
add power. (I know its possible but it seems rarely used)
I imagine, say, if I have some speakers that need power for something(say
some lights or maybe an active filter) but instead of running an extra wire
for power(and I'll probably need one for ground) why I couldn't just run the
power over the same analog audio lines.
Since the power is DC I could just use a cap to drain the power into and
another to block DC for the audio part? (of course this is for analog stuff
but I figure the same could be applied to digital)
I do realize that noise would probably become a much larger issue but I'm
sure there are other things and such... which is why I ask.
