With copyright law, what if say everyone only uploaded a certain percent. I know it sounds like BS, but to get around the current laws.

Say you limit everyone to 10% of a movie or song, then no one would be sharing it in its entirity?

Course they would still get the full file, but no single person would EVER be giving out the entire file. Which means, you would need several seeders, but that is almost always the case.

Also, bitto doesn't leave you open and show you what you have downloaded like most other p2p programs and once you are done upping, simply close that tracker and you won't be going back. I prefer it to my PC sitting online to a large p2p network all day.
