One thing I always wondered about was sending along metadata with the payment. For example, if a platform wants to accept payment in Bitcoin, but needs metadata sent along to format the billing properly. Sounds like lightning network might be able to provide some options.

Good questions! You can embed metadata in Bitcoin transactions today using OP_RETURN. There's even a website dedicated to it: http://coinsecrets.org/
With Lightning it's still a Bitcoin transaction so you could do something similar, or there's potential for adding an additional "off-chain" metadata layer on top of the signed transactions as well... definitely an interesting use case that would help avoid blockchain bloat too :)
