[snip lots of fields]

We had a request on the KMM list a while back for tracking Beta. It is the way 
that volatility is measured for the CAPM style models. Folks doing portfolio 
analysis tend to like that particular statistic, and Yahoo! has it on their 
pages. If it is easy to get in the csv, I would say to grab it as well.

ACK. Historical quotes are a slightly different animal from current quotes, but 
it is an area that has not yet been addressed in KMM. I do not know if other 
apps have some code that would help, though.

It is normally better to have more work than schedule. It often makes for 
amazing results, and if the work does not get finished, it makes planning for 
release n+1 easy :-).
