Um, yick!-)  The idea of using a bar-like representation of the assessment
strikes me like suggesting presentation of the info in a graph, and then
screen-scraping to evaluate the graph.  Aieee!

How about a spam-estimate of 0-9?  Pretty darn easy to match.  I wouldn't
imagine the lack of precision is going to be a problem, in this domain...

Or is this all too off-topic?
