How to implement LeadWatcher without violating terms of use

[wook74]

I'd like to implement something similar to the LeadWatcher example.

However, I notice that LeadWatcher doesn't have a "clipped from Google"
attribution, and I can't find an API call to get an attribution.

Is this OK? The terms of use seem to imply that an attribution should
be included. Or does that only apply if we're using the .html property?
I definitely don't want to violate the terms of use -- I guess I could
say "I was just copying LeadWatcher," but I'd rather make sure before I
get in trouble!

Here's the full bit from the terms of use: "You agree that you will
not, and you will not permit your users or other third parties to: (a)
modify or obscure the text, images, or other content of the Google
Search Results; (b) modify, obscure or otherwise disable the
functioning of links to Google or third party websites provided in the
Google Search Results; and/or (c) modify or obscure the attribution
language provided with the Google Search results (such as "clipped from
Google - date" or such similar language as may be used from time to
time)."

Thanks!
