Since others are mentioning commercial open-source models and 
that guy asked about using a more liberal license, let me mention 
another newer model.  Develop most of the codebase in the open 
under a permissive license like MIT/BSD/Apache but keep some of 
the features or patches closed, particularly those that would 
most interest potential commercial licensees.

This is the model used by Android, the most successful open 
source project ever, where AOSP is released as OSS then the 
hardware and smartphone vendors add their proprietary blobs and 
patches before selling the entire software bundle.  It's probably 
the best model if you want to be open source, get wide usage, and 
still have good commercial possibilities.
