As sad as it is, the current rules and gameplay prevents intelligence factions from actually doing intelligence. One way is it pre-arrange espionage with a certain faction but that requires approval on both sides which is difficult as noone wants to be spied on voluntarily save for few exceptions.
I guess, you can also organise expeditions into Omicrons/Sigmas/whatever, the no-man's land. This is noting new but good for entertainment, activity, and won't invoke wraith of other Houses most likely.
As counter-intelligence side of activity, you can also agree to do some pre-arranged RP either with Liberty corps having an inside agent from other corp/House, or a Libertonian working for other Houses, or some corrupt Libertonian politician, etc. etc. Again, the biggest problem is this RP by rules has to be pre-arranged not to be meta and thus losing its charm.
