Anyway, the rest of my prior post wasn't all that interesting but I would
also suggest you can read the literature and find problems. 

http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed&&term=blast+limitation

just skimming hits, there are new lab techniques and these may have artifacts or
quirks that need certain ID features. Alternatively, if you can find a specific confusing result
and sort it out with your technique that would be a good proof of concept.

Don't immediately dismiss this approach as there is so much new literature these days that
there may be problems and solutions waiting to be matched as research groups are too busy on
their own or different matters.
