Thank you for all of your responses, they have helped a lot.
One thing that interests me is how much analysis would have to be done to
distribute the graphs? ?For example, would posting a simple graph of the
price history, or the spread between two futures be acceptable without
license? Or would only more involved graphs be acceptable?
Thanks again,

Agreed. My response merely aimed to dash some cold water on your statement
? take advantage of 'loopholes' in the data pull methodologies provided by
? Yahoo/Google/etc.
as this is in fact not a loophole. The cgi interface at Yahoo! is fully
aware
of people programming against it, and I have both supported that interface
(via the Finance::YahooQuote module in the godforsaken Perl language) for
users, and deployed it daily myself for about a dozen years. No issue
there:
Yahoo pays, we get to use it, I doubt we can redistribute, consult a lawyer
for details, news at eleven.
Andrew also asked about the dissemination of derived analysis (graphs etc).
which I think that is fine because that is your work rather that their raw
data. ?IANAL.

PS There was also a 'not' missing in my 'program easily against ajax-y'. It
is not easy, or we all would have 'free' quasi-real-time data now.
