Are TCP extensions middlebox-proof?

Besides the traditional routers and switches, middleboxes such as NATs, firewalls, IDS or proxies have a growing importance in many networks, notably in entreprise and wireless access networks. Many of these middleboxes modify the packets that they process. For this, they to implement (a subset of) protocols like TCP. Despite the deployment of these middleboxes, TCP continues to evolve on the endhosts and little is known about the interactions between TCP extensions and the middleboxes.
