I found this good analysis of BitTorrent technology via the A VC blog. I liked it because it covers the good & bad of BitTorrent technology and that it is very close to my experience. I can get it to work very nicely, but my set-up instructions to my friends (techie or non-techie) are long and often “mystical”.
Overall, I believe there is a spot in the market for download movies. But this post definitely nails some of the issues. I guess I’m too techie and patient 😉
