FWIW, I believe that multi-asset LN will fail for a related, but different reason: to prevent long-lived spam payments we may require proof that something went wrong (ie. channel unilateral close tx). That won't be valid if it's from a different network, resulting in the exchange point itself being penalized. Thus they are vulnerable to such a DoS. Cheers, Rusty.
