I don't think there will be any interest, because there's no reason to 
deny any application access to the internet. I don't know of any Linux 
softwa

What proprietary Linux application would that be? I know plenty of Windows 
programs that aren't decent enough to allow access to the net, but we're 
talking Linux here..

Anyway, if anyone would ever want to have something like this, he/she 
would need to implement it in the Linux kernel. KDE has no control over 
which applications can access the internet and which can not, which is a 
Very Good Thing (tm). Once the kernel has support for application-level 
blocking, KDE might be able to negotiate between kernel, user and 
application about network access.
