Okay, here's one I can imagine, even if it might not be politically 
feasible:

The RIRs pay the Tier 1s to all run PTRs, using fees charged to people who 
get EID space from them*.  More people using LISP, more traffic, more fees, 
more PTRs...

And another one:

The Tier 1s decide that the cost of deploying PTRs is less than the cost of 
upgrading routers to handle the routing table growth that will happen if 
LISP doesn't get deployed widely.

So, that's two business models that I can _imagine_, even if I'm not sure 
they'd necessarily work in practice.  I'd expect there are other models that 
I haven't thought of yet and that someone will find a way to make money, 
somehow.

It's not that simple.  It's a very strange world out there...

I once knew a colo shop that ran an IRC server specifically because the 
traffic from the near-constant DDoS attacks (which IRC servers naturally 
attract).  The nature of the content biz is that they naturally send far 
more than they receive; _any_ inbound traffic they can attract is good 
because it helps balance their peering ratios, which makes other networks 
more willing to peer with them, which in turn saves them money on transit.

(* I assume the RIRs would distribute EIDs.  That also means there would 
likely be five different EID prefixes and five databases, but that's not a 
meaningful change to the technical model.)
