Here's an interesting legal issue if the copyright dictators succeed in banning P2P software:
Now, IANAL, but it seems to me that a legal hitch will exist here: Microsoft Windows comes with built in filesharing capability: the ability to connect PEER TO PEER with another machine for the explicit purpose of sharing files between computers. Windows also comes with FTP capability, having a built in FTP server and client.
This effectively means Windows is a fileharing, peer-to-peer program.
If the copyright dictators succeed in outlawing P2P filesharing, they will effectively have made the Windows filesharing capabilites illegal. Since Microsoft is one of the dictators, it would be really interesting to see their reaction when this gets chucked in their face!
