Well to answer all of your questions Niagra...
1. Why? Well I have always wanted to start up my own little amateur porn site (regardless of if I were making profit or not).. Only problem is I can't find any willing girls who will jump in front of a camera and have a lil solo fun (not even when I offered a hefty cash prize) and I had some insane feedback when I posted a vid of myself a while back (had the space I was hosting it on run out of its 20 gig of bandwidth in about 2 days and the vid was only 20 mb or so) and so I figure if I can't find any willing girls ... and people seem to like my vid ... I could star on the site...
2. I have the hardware and I certainly have the knowledge to do it all (I'm kinda a nerd).
3. I have been making websites for close to 5 years so I definitely have the website skills.
4. Copyright Knowledge is the only part that I am lacking in... when I sit and have a small read on it I can't see how I would be in anyway breaking any copyright laws considering the footage that I would be providing would not be copyrighted (as it would be me in the film, I would have recorded it and I would have no intentions of selling it to make profit).
I think that just about covers all of your questions
Thanks for replying and asking some questions though Niagra...Feel free to ask some more if you want to..
