Most of the legality of the 10th Planet system has already been covered in this thread. Locks that target the spine and most leglocks are prohibited in the majority of grappling tournaments, especially at the lower levels.
In the interest of full disclosure, though, it's worth mentioning why the 10th Planet stuff doesn't see as much play in the top tier grappling game.
One of the major problems with Eddie Bravo's game is that it requires extreme control of the basic position before you can effectively utilize the advanced position the way that he teaches it in 10th Planet.
If you don't have a deep closed guard, with the posture broken down and your opponent's hips underneath your hips, and legs up high, even getting to mission control is really tough. It's a great position when you can get there, and against guys who are going to try and stack, mission control is a great way to make sure that you don't lose the position that you've picked up, but against a grappler who knows how to defend from inside the guard, getting to mission control is going to be a rough time.
The same is true for the lockdown position that Eddie teaches from half-guard. It's a really effective position, but (a) it's pretty tough to use effectively against someone who keeps their base in and (b) it's tough to get on the side so that you can attack effectively from that position.
There are a lot of other reasons why I don't recommend guys start with the 10th Planet system as an introduction to grappling. The top tier of grappling right now is a pretty clear demonstration that going far in grappling depends on a solid grounding in the fundamentals, and at that point it's good to innovate. But you have to get to a place where the fundamentals of the basic positions are solid before it really becomes a good idea.
