If I'm not mistaken, oddcast sounds like it's doing both, encoding and
capturing and has the code to edit tags.
Since I'm writing a second program to capture a 2nd devices output for
tags and then using line-in for alsa, I don't think using libogg for
this is possible, because I'm not calling the fork. Ices is.
So I've got two programs. Ices records line-in on alsa interface.
While my program gets the metadata info from serial port (/dev/ttyS1)
then writes this to ~/.dsctl/metadata. Once done, SIGUSR1 to ices
process & vola! done.

Would require having the user specify user/pass, but is another way. I
think there was a hiccup with this method as I did the research a couple
of days ago. One issue, I couldn't simple just cat the info into an
http address <darn>.
