I used to work at a large ISP with exactly these kinds of sales  
people. They have a hard time taking "no" for an answer from the  
engineers, but when the engineers say "sure we can do it but it isn't  
going to work" and then, lo and behold, it doesn't work, they tend to  
catch on.

I.e., you can pay YOUR ISP to route your ULAs, but that doesn't mean  
the next ISP is going to accept those advertisements.

Obviously unbelievable amounts of money will make a difference here,  
but how does it make sense to go visit all the largest ISPs handing  
out money if you can get a PI or PA block much cheaper and easier?
