That technology was supposed to be IPv6, PA-only. Unfortunately it was
launched before the quest for a working PA-only multihoming solution
ended up returning with nothing.

Back in these days, there was also a feeling that IPv6 would be easy to
deploy, and if not easy at least a lot easier than replacing BGP. 

I think that another very important message for the ARIN community to
understand is that replacing BGP is a HUGE undertaking.
