Actually, I would like to allow users to use either the 64-bit Cisco VPN client or the Windows 7 built in client. Is this possible?
Additional information: The IOS host is the 881w-A-K9 ISR running version 15.1(4)M4.
There is no current VPN configuration.

I asked this question a year and a half ago, but I still do not have enough information to complete this task. I want to use the built-in L2TP/IPsec Windows client to dial-in to my router. The accepted answer to that question doesn't actually cover dial-in scenarios.
My immediate question is if this is even possible. It's hard for me to believe that it isn't, but this pages says:
Client-initiated tunnels using the L2TP or L2TPv3 protocol must be
initiated by a router configured as the local peer. The L2TP and
L2TPv3 protocols are not supported for client-initiated tunnels from a
client PC.
However, this page, which is older, doesn't make any such warning. What is the authoritative answer to this question?

To configure IPSec with the native Windows7 client, you need L2TP + IPSec on IOS and Windows 7 L2TP + IPSec.
