Our IPX over IP encapsulation scheme solves problem 1), i.e we use
UDP with checksums.
However 2) and 3) are "as is", i.e "dumb" in our solution.
One way to get rid of RIP and SAP would be an encapsulating router that
derives the RIP and SAP info from a link state protocol on its WAN port
and advertizes this information on the LAN port as usual.
