I don't think the business model is a big problem or there is no incentive
for the end user to upgrade their hosts. 
Provided the LISP-CONS/ALT is just looked as a transitional solution to the
routing scalability issue, the non-upgraded host will suffer the initial
packet loss/delay pain, on the contrary, once the host is upgraded to
support EID-RLOC mapping query on behalf of the ITR, the end user will jump
out of the pain. Besides, it will benefit the ISPs eventually since they do
not need to afford the high-cost ITRs which should support full database (
e.g. LISP-NERD), or which should support cache and this mechanism will
become a target of DDoS attack.
