+1 for PI usage, however, seems some have difficulties getting it, as you need to be RIPE (or other region) member (not free-of-charge) to get one and an ISP is not always really "happy" to do this (as they become a little more independent)

You don't need an ASN to use PI space.

We have a few customers in the same situation. So we obtained a PI prefix for them, which costs next to nothing in the RIPE region at least, and advertise the prefix on their behalf (and in the cases where there's a second upstream, the second upstream does the same). Works perfectly well, and is much less complex than anything solution involving ULA, NAT, multiple prefixes on the hosts, or whatever. The customer just gets a bunch of addresses he can use in perpetuity.
