These transactions work fine with the lightning network, according to the author on reddit: https://www.reddit.com/r/Bitcoin/comments/47rk85/first_succe...

So this can scale as much as lightning can. See https://en.bitcoin.it/wiki/Scalability_FAQ#Doesn.E2.80.99t_L... and https://blockstream.com/2015/09/01/lightning-network/

Additionally, lightning actually uses the HTLC (Hashed Timelock Contract) transaction style that is used by ZKCPs. I believe it is used to extend lightning channels to multiple hops.
