VPN overkill?

["Ted A" <arcturous () hotmail com>]

All,
First off, good fun reading this list. Some really great advice and good 
thinkers on here. Thanks for the great questions and great answers.

So here's my issue. I have an IT infrastructure manager who has raised a 
requirement I find myself questioning.
We have a goal of connecting a remote office to a central office via a VPN. 
This manager insists that only acceptable way to accomplish this is by 
connecting 2 VPN concentrators. I debate this, noting that a PIX should be 
more than capable of handling this connection at the remote office and the 
only place the concentrator is needed is at the central office.
Am I completely off my rocker, thinking that a second concentrator for a 
single connection is a little overboard?

Thoughts?
Thanks,
Ted
