I'd think that going with two tagged VLAN's is the better route. You will then be forcing the customer to adhere to the VLAN's that you have specified and reserved for them. It's also a security advantage because if you go with untagged, who knows if someone might be able to vlan hop/double tag their way into someone elses network....

But it's bugging me that something could go wrong by not having untagged native VLAN that I can't think of.
