Create a VPN between the two networks. Use brctl to bridge the vpn and ethernet interfaces on each side.

Found brctl in bridge-utils, will try tomorrow. –  Dmitry Jan 12 '12 at 15:46

What type of connections are you trying to merge? Is this for two directly attached networks (say a multihomed Linux box) or is this two remote networks?

You might check out L2TP (Layer 2 tunneling protocol) which is commonly used with IPSec VPNs
