Maybe I am not reading your response right. From what I read your saying you need both peers tunnel endpoints to be in the same subnet? If that is what your saying that is incorrect. You do not need to setup addresses in the same subnet on each end of the tunnel. You simply identify you encrypting peers address which can be any accessible address in any subnet. As well, the router that you define as your peer simply has an access-list that defines any traffic passing through it that gets encrypted. This is based on source and destination and can be any source any destination inlcluding subnets that this encrypting router is not directly connected to as long of course as the traffic passes the encryprting router on the way out, and the destination is accessible. On the Microsoft W2K thing. I would avoid it if you can. It is a little more complex in that you have to setup L2TP on the router and the W2K and configure IPSEC to use the L2TP tunnel. It will be much easier to encrypt from router to router based on access-lists. The access-list will only define what get's encrypted, and is not applied to any interface just the Crypto map. You do not need any special hardware unless your VPN network grows considerably large and you are using 3-des. Then you will want to look into the PL2 or PL3 card which will take the encrypting decrypting engine process of the routers CPU and put it on the PL2 or PL3 card.

PS: You don't even have to setup a routing protocol just a routed protocol......Keep in mind that all of your static routes would have to be setup properly......
