site to site vpn over a bridged link

I have a multi-point wireless bridged link that needs to have all traffic encrypted over a vpn tunnel using the ASA 5505.

All ethernet segments are in the same address block as there is no reason to use different blocks as this is a bridged network.

Is this possible and if so, how do I set up the ASA's?

I have enclosed a diagram. I have also tried to explain to the customer that there is no need for the ASA's since I can encrypt all the traffic with the bridge's using AES, but they still want it.

Seth,

1) Is the "outside" interface of the ASA's on the same IP subnet?

2) Is the "inside" network on the ASA's all on the same IP network?

In this case, the inside interfaces of both ASA's would be in the same network. I can setup the outside interfaces to be in a separate network.
