I like msm's idea about info on starting a paysite. I'd really enjoy a comprehensive tutorial specifically about hosting for paysites. For example, there are formulas out there for calculating bandwidth (using total of text, video, and photos divided by number of users, blah blah) but that's all theoretical. How about realistic expectations for novice paysite webmasters. Something along the lines of "a typical new site with 10 affiliates promoting it and normal SEO may expect 1000 visits per day, 500 of which will click through for the tour. 50% will view everything, the other 50% will view half of the offering. If the tour has an aggregate total of 10 MB of text, photos, and videos, that means 3.25GB per day just for tour promotions. Now let's look at typical member daily usage of the site..."

Fill it out with charts for some typical patterns or examples (small site, medium site, new site, established site, how many existing members log in daily, how much they download per day, etc.). I know this industry is pretty close-mouthed about publishing actual numbers but many of you seem very knowledgeable to me so I would hope you could give some rough estimates. As it is now, a newbie can only make a wild guess about what kind of hosting plan will be needed and hope that it won't be either too much (costly) or too little (costly when members get fed up with slow access and quit).

Of course, it would be totally cool if you added stuff like the cost vs. benefit of hosting galleries for affiliates (I imagine they suck a huge amount of bandwidth but do extra sales typically turn it into a profit instead of liablity?), how many users can various server configurations service simultaneously, when and why would it be advisable to split services among more than one server for a site, etc.

If you can do all that, you'll be my new hero
