What's more realistic is you have to get a single /48 of PI space for people to carry that globally.
I fail to understand what difference it makes to a router whether a /48 is from PA or PI.
And if you have 5 discontiguous networks, what the RIRs should do is carve a /44 out for your present and future PI allocations and issue you the 8 /48s;
Well, they carve out a /44 and issue you the /44 in most cases that I am aware of. Is that a problem? If so, why? Seems rather silly.
the PI /48 routing slots that you have justified need for -- arranged so that they fall within the same /45.
RIRs don't issue routing slots. They issue addressing blocks. Usually (though not always) these addressing blocks are aligned with prefixes. Sometimes those prefixes end up in one routing slot. Sometimes more. Occasionally, none at all. There is no definite relationship between network blocks issued by RIRs and prefixes and even less so between prefixes and routing slots. Owen
