The 'remote sa' as simply a proprietary UD protocol.  Whatever data two 'remote 
sa' services exchange shouldn't matter, nor should the fact that each issues 
local SA path records.  There's nothing magical about this.

If I have an app that can query its local SA, there's nothing that prevents that 
app from sending that data to whatever peer it can connect to.  It can even send 
the data over TCP if it wants.  Keeping the SA subnet local doesn't add any real 
security.

Coming up with a solution that doesn't work with any existing hardware, targets, 
and SAs isn't very useful.
