Currently the only thing the blockchain are Bitcoin transactions. You can call that payload, if you want.

Sorry, but I didn't read all pages, only the beginning and the end.
Can you link the post explaining who would rationally provide for the upkeep of a separate chain?
The expense of any chain is storage in the form of disk space and defence/upkeep in the form of compute power/electricity and bandwidth.
This must all be financed by the hosts = miners.
Bitcoin would still hold a special position, because it would be the unit of accounting for all other "transactions".
For example, for a BitDNS transaction with fee, you'd also need a Bitcoin transaction, solely for this fee.
The ability to use the blockchain as a service would provide a kind of real backing for Bitcoins.
Do you think that it would be too much data? The miners surely can meet supply and demand.
Isn't
BitDNS Bounty (3500 BTC) for a system of this kind?
I'd start development, but I haven't even compiled Bitcoin, yet. Has somebody a guide for how to compile on Windows?
Starting from scratch is a little too much.
