A [shellcode only] example of this can be seen here:
http://www.darklab.org/archive/msg00183.html

A couple of useful links that give an overview of the SEH itself:
http://www.jorgon.freeserve.co.uk/ExceptFrame.htm
http://www.microsoft.com/msj/0197/Exception/Exception.aspx

FWIW, you may want to hunt around some VX source as the VX folks have been

http://29a.host.sk/ezine.html is probably a good start.
