IMO I don't like the idea of building on top of another network like steller, I feel that piggy will be strong enough to have its own network.
To clarify - Neither do I, that's not the proposed plan. PIGGY's ledger at a specific block height will re-genesis onto its own new blockchain.
Since there has been no other proposals I will begin formulating the specification and bounty.
... Excitement ...

Man I hate writing Specs, anybody want to do this for me??? Heh.
