What is needed is that someone 
1. makes a list of the authors
2. contacts the authors and asks if they agree to LGPL relicensing and
   if so find an agreement about the share of the money for each.

once this is done we can discuss what to do about code that was
written by people who have not replied.

please concentrate your time, if you want to help on 1. and 2. and
not some later steps that might for all we know be unneeded.
Also if you no longer want to help, please state that clearly so
noone waits for you to work on this.

Into a blind darkness they enter who follow after the Ignorance,
they as if into a greater darkness enter who devote themselves
to the Knowledge alone. -- Isha Upanishad
