Do you mean, there will be some special LN variant or service specifically for cross-chain operation (i.e. "edge of the network")? >Moreover, there are two general problems with random currencies on >lightning.

By "free", do you refer to the fact, that most altcoins have low or practically 0 transaction fees? >Finally, we're trying to close down spec changes, so we're reluctant to >add features to 1.0 if we can avoid it.
