Hi Albert,

While it is not unique as you mentioned it is unique in comparison to traditional routing techniques. In addition the ability from the owner of the EID having the ability to specify how load balance/distribute inbound traffic is also a benefit we get from the pull model. I do agree we need to hit all 4 as you mentioned, but most end users who evaluate LISP in my experience usually highlight that the pull model and being able to control traffic inbound is a key reason the decide on LISP. With that said I believe it should be considered for addition in your document based on this. 

My 2 cents,

Chad Hintz
