What the person wants are shell accounts in exchange for access to a ftp dump site with all the pirated software.
You obtain a shell account by either purchasing one [about $10/month] from a shell provider or by running a *nix box connected to the internet via broadband. Shells are used for a variety of purposes. Most likely the person wants to use the shell for either running a "bot" using eggdrop [
www.eggdrop.net ] or using the shell to move files between computers [ since most shells are connected on high speed lines ]
I used to have a few shell accounts I used to run bots. Usually bots are more for 'show' than any real use
