We deployed ULA+GUA in our environment, a mid-size cable ISP. We also
prevent ULA-GUA communications at the datacenter edge. So far it's 
been working very well, only found one instance of bad source 
address selection in a product. 

Btw, we have plenty of ULA-only servers and devices. No problem on 
that side, but of course, we'd have to disable IPv4 to be really 
sure of that. ;)
