All,
In this morning's meeting with my employer, I had to confess that
technical support for liquidsoap would be slow because it was
mailing-list based for an open source product. While I was willing to
wait a few days for someone to take a stab at this, my employer is not.
I am now required to find an alternative solution that "works out of the
box". I therefore withdraw my request for help with the issue that is
detailed above.
Please know that the matter is unresolved and for the sake of your
community who may need to syndicate live MP3-based radio streams between
providers, I hope that you spend some time looking into it.
Thank you and good-bye for now,
William
