Another project I am working on has a need for a "line amp" 
card. 

The project is listener supported community radio.  There are a 
bunch of community organizations all just getting started, all 
on very tight budgets.  I am looking into a group project to 
design and build equipment.

A good "first board" could be a line amp card for the project.  
It's just an op-amp, output buffer (2 transistors), voltage 
regulator, some protection, ....  By bringing out the correct 
pins, it can be configured several ways.  I count 16 parts.

Recording studios, radio stations, and TV stations use lots of 
cards like this.

After this, there are bigger things in the works.  We are trying 
to make possible a complete radio station with free/open-source 
software and either commodity or open home-buildable hardware.
