Interesting. Might be a little hard to block. If we catch anyone using P2P or any programs on our "bad programs" list we set them up in their own OU and set the "Run only specified apps" Group Policy Object. (Thus not allowing them to start any .exe we dont specify) We are a smaller shop though and can do this easily.

Comes with a build in webserver:

"• Integrated Web Server Makes Sharing “Sets” of Files Easy. Sometimes you want to share a "set" of files that all belong together, files that interlink and have relation to one another. The most efficient way to do this is for these files to be placed on a ãwebsite.ä To facilitate this, ES5 provides its users with a built in web server to permit the user to create a ãwebsiteä for these linked files. The files shared through a userâs ES5 web server will appear when someone searches the ES5 network. When located, the ES5 downloader accesses the users own ES5 website through the ES5 integrated web browser. For additional security, users can place passwords on their ES5 enabled web site providing access only to other users granted permission to do so. "

Wonder if this will cause problems with users on the net with a cable connection and no firewall?
