talk to You Need A Budget.
Would be nice to have splitwise handled as a bank account within YNAB. Or within any other budgeting app really. I guess what i'm saying is pretend you're a bank and offer an API which gives third party apps a secure, read-only view of 'transactions'.
We do have a public API off of which YNAB could build: http://dev.splitwise.com/

I would love this! This would make YNAB my favorite budgeting app ever. I record a *lot* of my spending in splitwise as I navigate a complex set of polyamorous relationships, and I'd love to be able to budget those without entering them twice...
