How Secure is Layer 2 ???

Here is an interesting question. I want to configure a Pix FW to provide a
controlled connection between 2 Vlans on a switch (Cisco 3550 or 6500).
There is no layer 3 routing enabled for the "outside" interface vlan so in
theory there should be no way to break out of that vlan.

In theory I can't see a problem but perhaps I'm missing something???

Cheers
Trevor
