VERY different!  When you encap inside GRE, you wind up with a lower 
MTU.  This is going to seriously break Ethernet networks that are 
bridged to that GRE.

To bridge Ethernet over a long-haul network like that, it seems to me 
that you need to encapsulate it in a stream protocol, so that you can 
preserve the local MTU semantics.

Of course, that has its own problems.  This is why I don't like 
"solutions" such as this :-)
