Cash Accounts, lookup service

[monsterbitar]

I am currently working on a specification for on-chain aliases that look like this: James#5721; to help convey payment information in a more convenient manner, particulary in verbal contexts.

Here's a link to the draft spec: https://gitlab.com/cash-accounts/specification/blob/master/SPECIFICATION.md

Would the insight server be a good place to add support for looking up such aliases?
