hmmm... can't say I'm a fan of cloning Jedi. I don't really see the Jedi as anything physically SPECIAL. Just people who answer the call and commit to the force. Otherwise we are headed down the midichlorian path. And that path leads to madness.

But I guess the bigger question is who would be doing this?

If its the enemy I guess I can understand it, like a mystical powers arm race.

If you mean the republic, I don't see Palpatine going for it. Remember he wanted to wipe out all the Jedi and would have killed jedi babies because their power could be a threat. Even if he created them to be under his control, I believe (again with the babies) he would be too paranoid that they would try to overthrow him.
