That's like saying there is a security risk in running two phonecalls in 
the same T1/E1. They're logically separated, it's commonly done.

Usually I'd say that the ISP will solve the handoff by having a switch or 
media converter to give you one port per service, but using vlans for 
logical separation has been pretty much standard procedure for 10 years in 
a lot of places.
