Know of but not implemented.

IPSec would be the way to go for this although it's not very 
communicative when things don't work right. In the 2.6 kernel BSD's
(or KAME's) IPSec stacks have been imported .. racoon from FreeBSD 
and isakmpd from OpenBSD. From the OpenBSD's man page on their 
bridging  utility (I haven't messed around with the Linux bridging
util) 
it mentions using protocol 97 and a GIF to tunnel the frames over IP. 
Here's the link:

Good luck to you in what you're trying to achieve .. it isn't easy :)
