In the future I hope they enable character transfers between accounts in TBC, coz now having a bunch of 60's scattered in a multitude of accounts is basically useless, I want to move them to the same account.

It's clear that they are not gonna do it in the short-term (coz people would abuse the shit out of it with the paid boost), but I hope they change their stance when the hype fades.

A good solution would be to allow it only for level 70 characters, so people can't abuse it with the level 58 boost, coz they would be forced to manually level the char to 70 before been able to move it to a different account.
