This looks like an excellent tool and one which I have been looking for for some time since I was involved with Firste and ENBA back in 2000 where we trialled something similar.
Unfortunately from my initial investigations it looks like my local bank needs to be affiliated with Yodlee for Mint to work and even though my bank's web offering won the "Best Online Banking Service 2007" I doubt they are up to speed on interfacing with 3rd party apps.
Additionally I wonder how Mint deals with non USD transactions and reporting.
Anybody on AAM ever try it or anyone know of another tool that does interface with irish banks?
