According to Sophos' latest press release Administrators will be able to block network traffic essential for the multiplayer online game Second Life using Sophos Antivirus very soon. The implementation of its application control ability allows to control which websites and online applications can be accessed using the PC. This service, which intention it is to raise productivity in companies, will start with integration of the 'Second Life'-strings into the usual updates on 22nd of March.
That is a pretty unusual approach - Second Life might have 4 Million users. But only around 25000 can be seen online at the same time at most. They should have started with World of Warcraft which has around 2 Million users online everytime. I don't get the hype around Second Life. It's hideous and there is nothing really appealing in it. But that might just be me...
