I'd argue handling it at the layer 3 level to be preferable than splitting
every customer into their own vlan.

If you split into vlans like that, if you have single-box customers, you'll
have to have subnet boundaries for every /30...

OTOH, vlan isolation for customers is pretty much the norm, as long as
you've got the IP's to waste, why not..
