When reveiwing proposals for a WAN solution.  What questions should I be asking, and what should I be looking for?

As one solution i using a VPN, and the other is using a BT's cable network.

As one proposal, has missed off internet access, and the other re configuring all our PC's to work on the new network.
And not just at the new office that some staff are moving to.

Our faith is somewhat jaded.

If a WAN project for which you have received proposals is supposed to provide Internet access to all offices there are two choices: every site has its own Internet access, or you have one controlled internet access.
You should not have to re-address all your internal PC's unless you have used IP address that are public addresses belonging to someone else AND you want Internet access. Or, unless you are moving some equipment from one location to another, of course they will have to be re-addressed for the new location.
VPN's typically travel over the Internet, terminating on a device at the customer premesis. Cable is also typically direct Internet access.
Ask lots of questions about the security of the WAN, and what else you need to do to your networks to protect your business assets. Do you need to purchase firewalls for every location?
Ask lots of questions about Service Level Agreements. What percentage of uptime can they guarantee? What kind of latency can they guarantee? Can they guarantee end-to-end latency?
