Yes, NAT is used to share a single IP.

Well, NAT is necessary if one wants to share a single IP. Basically MOL lives
on a private network which is world-visible through NAT.

I have thought about implementing something at socket level, but I can't 
see any real benefits from doing that.

The sheepnet driver is an alternate solution. Basically the ethernet interface
is shared between MOL and linux. Separate IP addresses has to be used for MOL and
linux. The sheepnet solution is mostly useful for AppleTalk and non-IP protocols.

(Btw. I have recently fixed the sheepnet driver. It now works with OS X)
