Ian stated the following requirements for a baseline codec:

- is implementable without cost and distributable by anyone
- has off-the-shelf decoder hardware chips available
- is used widely enough to justify the extra patent exposure
- has a quality-per-bit high enough for large volume sites

I believe this is a reasonable summary of the requirements that have  
been stated by various parties.
