Hi Peter, I've been mulling the idea of attaching work to low fee txns, both as a compensation (e.g., in a sidechain, or an alt), and/or as a spam proof. Unfortunately, both suffer from ASICs: For spam proof case, the adversary can easily buy a used/obsolete device to produce lots of spam txns very cheaply, unless you put the bar very high, making it almost impossible for average users to even try. The compensation scenario is pretty off-topic, still, interesting enough for 1 min read: Wallets commit to the latest blockchain state in the transaction AND attach work. It is considered contribution to the security (illegitimate chains can't include the txn), hence isrewarded by fee discount/exemption depending on the offset of the state they've committed to (the closer, the better) and the amount of work attached. For this to work, block difficulty is calculated inclusive with the work embedded in the txns, it contains. Sophisticated and consequential, yet not infeasible per se.
Unfortunately, this scheme is hard to balance with ASICs in the scene too, for instance, you can't subsidize wallets for their work like with a leverge, because miners can easily do it locally, seizing the subsidies for themselves, long story, not relevant just ignore it.
