One of my players is developing his own Corporation?, Anyone got any ideas about player-owned groups? Options

Hi Dumpshock, I've just recently began posting here but I've been lurking for a while now. I love some of the responses I see other GMs get and have stolen too many to name. So thank you guys for what you've already added to my games. (IMG:style_emoticons/default/grinbig.gif)

I currently run two games, both 4th edition. I've been running my first campaign for about 3 years now, it tends to be more of a character-driven/meta-plot type game. I actually converted a group of friends who were into DnD at the time, of course after playing SR for a short while they quit DnD altogether. (lol) And more recently I've started what I call my stand-alone campaign where we do a more Seattle-based, traditional style, usually involving a run per session with downtime for character development in between. I love both games and the weekly style change helps keep me fresh I think. The only real problem I've had is the back pain from carrying around my backpack full of nine books at a time.

In my first game I actually have two players creating their own "associations".

I have a bit of a power gamer PhysAd who now has a 50 man strong ninja clan based in Hong Kong. (Anti-corp hooder sort of group.)

And a mage face who is developing his own Corporation, (He plans to use subterfuge to bring a world corporate war that he'll profit from and hopes to reach AAA status eventually.) both were developed in game over time.

I love the idea of the characters being able to amass people around their causes making them more important in the SR world. I think it brings new roles and options to the players. It really gives a feel of variety to the story overall. The only problem is I worry if kept unchecked without some hard rules it could get out of control. I'm currently using and expanding on the advanced lifestyle rules and making checks for overall development of the groups. Even rolling social checks for Important members and such.

Anyone have any ideas on how I could knock their associations down a peg every now and then?
