I don't know how much more mass Jupiter would require to ignite – twice as much, three times (without obelique assistance) but it's not going to intefere with the formation of the other planets much.
Thanks, Chris! As I said, I've not looked into this sort of thing much in quite some time, so my memory on it was somewhat vague... so I appreciate the refresher/better information!
