It already does this.  TCP/IP connections don't break when the layer 2 link 
is broken - your application, client or server, might decide to time out if 
there's been no activity for a while (usually around five minutes or so), 
but TCP/IP won't disconnect you.

Unless, that is, you're on Windows, where the Microsoft TCP/IP stack has 
chosen to act on "Media Sense", and will terminate all TCP/IP connections 
on a NIC when the cable is detected to be missing.  On all other operating 
systems (and non-default Windows systems), if you kick a cable loose, and 
re-plug it, your session will continue.

Alun.
