[Procrastes]

I was just mulling over this same problem last week. This approach is a big improvement over giving Mint or Wave (or their scraping partners) my credentials.

Last I looked GnuCash didn't support any online banking except HCBI (Germany). So beyond the simple online finance manager functions, maybe it would be worth thinking of re-purposing this as a banking transaction aggregator that could feed GnuCash or Ledger or whatever. That would give it a better focus on the value for me, at least.

What I would really like to see is a startup or open source project that can sell banks on a standard API with granular OAUTH and drive that difficult adoption cycle. Something in the spirit of the German HCBI, but built on REST with the ability to limit an app's access to read-only, get balance and get transaction options.
