My thought is that running it outside of the DS my bandwidth wont be monitored/throttled. Are there any other ideas? Is my idea Illegal?

The FMS makes no distinctions between the types of traffic being sent between the the DS and the robot. All data transferred, including basic robot signaling, are included the the 7mbit limit.
Some parts of R60 to note:

A. Network Ports:
viii. UDP/TCP 5800-5810: Team Use, bi-directional

The rules specifically allocate a range of ports for teams to use in any way they wish. These ports will be open to any kind of TCP/UDP traffic you can ask the DS and the robot to engage in. For example, a web server running on the roboRIO separate of the other robot code and a custom viewer program running on the DS could communicate over these ports. Any and all traffic fall under the limit. You can't 'get around it'.

While FIRST makes every effort to provide a wireless environment
that allows teams access to a full 7Mbits/second data rate (with about
100Kbit used for ROBOT control and status), at some events wireless
conditions may not accommodate this.

We have experienced this personally. When using 4.5Mits/sec for a relatively high resolution camera feed, we were instructed by the FTA to decrease our bandwidth usage, as ours was "much higher than other teams". So to be safe it might be wise to plan to use less than the 7 alloted. That being said, we have never had any trouble doing vision processing on the DS and meeting this limit, so I would imagine you could figure out a way as well.
