No need for me to defend my pipe dream, but a few lines since it's free.

I think the cost, per year, of my idea would be = or < what you pay for a full version of Poser and all the extras that you buy that just take up space and often only get used one time, if at all.  I personally prefer all this crap off my storage devices, for the most part, I do get very tired of buying new Hard Drives and that whole rigamarole. 

Further, the idea that the render will be EASILY shared on a vast network on the internet itself, rather than bog down my own machine with 100% of it, and that alone would be worth a monthly 15 dollars IMO.

Edit to add:

I have a real time justifying Poser purchase to the Mrs. every 1.5 years.  50 dollars up front and 15 a month goes under the radar.
