Hey Robert,
This is a really popular feature idea. Although they may not fit the mould of a conventional ‘joint account’ we will be working on features which will make it a lot easier to send, share and save money together. Bill Splitting between users for example, is one feature on our radar which we hope to introduce in coming months.
The idea of linking two accounts has been discussed at length here, it might make for some interesting reading! Joint Accounts 5
