Christian,
you are absolutely right. However,  avoiding any impact on the users has been the number ONE objective of LISP.
And now, by moving even to LISP-DDT,i.e. dumping allegeable worse variants, the consequences will be disasterous.

I think that we are giving up too early on the feasibility of updating all
hosts. Indeed, any substantial change in routing and addressing would most
probably end up changing all hosts, or at least most of them. I also think
that a research group should not necessarily shy away from investigations
that affect all hosts. If research comes out with a brilliant shiny star on
the horizon, then engineering might follow. If the best we can do is hack on
the edges of current solutions, then engineering groups can definitely do
that, no need for a research group.
