I know for a fact that an extremely large tier 1 routed RFC1918 address 
space for an extremely large cable company at one time (and no, I don't 
mean 2547 or anything like that).  I have no idea if this is still 
occurring, but when this very large cable company needed to use more 
private addresses they actually would ask the tier 1 for an assignment in 
order to avoid collision.

I don't see the problem with ULA though, sure, someone will route it, but 
not everyone, just those getting paid to.  It's actually the perfect 
solution to routing table bloat as there is a financial relationship 
between the parties that announce space and the networks that carry it.
