Sounds like Gridcoin. The problem with these systems is that it's difficult to write a useful proof-of-work scheme that produces useful work as side effect. So you have a loss of decentralization vs conventional cryptocurrency, but at least you have "fairer" distribution compared to proof-of-stake alone.

The "Offer" Model presented just seems like a conventional multisig escrow, presumably with the blockchain serving a as a signalling mechanism?

There is no proof-of-work or proof-of-stake involved. There is no consensus required. This is a marketplace. The blockchain is used to handle and log transactions.

the offer model will require a multisig escrow, but with some additions. We need to be sure that when someone buys compute, the same computational resource is still available. To solve that, you can use a fair exchange protocol.
