I expect that to a lot of people bitcoin being a "person to person" (p2p) currency is a major part of the "contract" they feel they entered into when choosing it rather than, say, Paypal or Visa or whatever alternative type of system for transferring value online.

So maybe we need to move to a DIstributed Hash Table (DHT) based system or something of that kind, that lets these ordinary people running nodes of a p2p financial network connecting them directly with various friends and family and other participants in the network do it without needing the whole blockchain?

Maybe we could even move the work into buckets grouping transactions into hash-bucket groups to form one block per hash-bucket or something if one cannot actually divvy up all the blockchain DHT style or RAID style effectively?

Otherwise the basic plan seem to be to pull a bait-and-switch, selling people on a purportedly person to person grassroots currency then pulling the rug out from under them by migrating it to business-to-business then to megacorp-to-megacorp...

For it to be a p2p network, I think we need to do something like look at the median, mode or mean home computer on the median, mode or mean home internet connection and ensure our limits keep it reasonable for folks to run full nodes on such systems without sacrificing their ability to run their accounting software and their word processor and their browser at the same time...

(Notice I do not say also stream a movie or even also listen to internet radio; I am content that they use their television and/or radio for that stuff. Heck let them use a telephone for voice chat too.)
