I'm not sure it would be possible.  Ie I'm a pretty knowledgeable 
developer in terms of IP.  But there is no way for me to keep track of 
all the patents in use and being filed.  Part of the problem with the 
system is the difficulty keeping in compliance.

I assume your sampling could not be automatic.  I expect a typical 
patent examiner or attorney could not do the analysis(ie does this code 
use patent A requires software knowledge).  Typical developer doesn't 
know the patent landscape.  I expect its a rarified person or requires a 
team to evaluate a codebase for patents.  Perhaps IP law firms do this 

In the end I expect most codebases violate many patents.  As a developer 
I'd also argue that many patents are "stupid", but that's a different 
thread.  If the cost of compliance was reasonable I expect some 
developers/companies would license a pool for the known costs/risks.
