I'm about to try this. I take it the crossed cables don't rub against each other, or at least if they do it isn't an issue?

It's normally a pretty low angle and doesn't end up mattering.
I've known a lot of people who have done this cross in front of the downtube on MTBs. There it's just a matter of making sure the cables don't take paint off the frame, but that's not normally an issue under a tandem boom tube.
