I think you mean how much will be passed on to us... I don't have any way of estimating. Jorge will have to pay $977.98 for 2,000,000 downloads which is outragepous when you consider all the installing, deleting, trialware, etc.

Doc, that link leads to the Beta section of the Winstep forums, which is closed to non-registered Winstep users (not Uvah's case, but others won't be able to read it).
Anyway, nobody will have to pay anything, Uvah. Weather.com must be off their rockers if they think a simple weather feed is worth more than gold, not to mention that their stated maximum of 2 million requests per month (*requests*, Doc, not downloads, lol) is simply not enough for any popular desktop gadget.
For comparison, Wunderground.com charges $500 per month for up to 1 million requests PER DAY - and that price is still too steep, IMO.
Anyway, mostly only weather forecasts will be affected on October 31st when they cut the feed, since Winstep applications by default retrieve *current* weather conditions from NOOA.
Now looking into other options, but things look a bit grim considering Weather.com only gave 15 days notice to everybody using their feed.
