Re:

There's some related work proposed in the IETF TLS working group.  The idea there is to bind cookies to TLS client certificates, so as long as the private key corresponding to the cert is only on one machine, the cookie can only be used on one machine.
<http://tools.ietf.org/html/draft-balfanz-tls-obc-01>

Of course, you could also just associate cookies with a client IP addresses on the server side...
