I think if you summarize Accountant's needs when working with Bitcoin, write a post about it, become a bridge between accountants and bitcoiners, then there's a chance that couple of developers may join you and work on an open-source solution with your help.
What I was always wishing for is a personal application which securely tracks and pulls all my transactions from anywhere, but it doesn't leak any single piece of my information to anyone and is well encrypted. I wish this app would then let me securely track what I'm holding, generate documents for FinCen, generate txf to import to accounting software, etc. But I'm not expert on what is the best way to actually track my finances and that's where help from someone who knows more would be great.
