I think it'd be great, although syntax could be problematic indeed if
"and" and "or" logic would be implemented.

Simpliest (from my pov) thing that comes to mind is perl / bash /
libpcap / etc syntax like "rule1 && ( rule2 || rule3 ) && ! rule4",
disallowing multiple values for the sake of unity (i.e. "Type=socket ||
Type=dbus" instead of "Type=socket,dbus").
