share money in SL, safes

I would like the possibility to share money in SL. Me and my friend hella have always had this problem in SL.
For example, I need money or she needs money, and it would be nice to have our common money at home. This could be done creating sorta "safes" accessible to both avatars.
Actually banking systems are available only to one avatar at the time.
Can somebody have some thought on that?

there are av shared safes available in SL, i've had friends who use them. don't remember the manufacturer at the moment, but they are truly available. according to the friends who had them, very handy, as well.

It's a simple script too. If you plan to share all your money combined, then it'd be a simple matter of everytime you click on it it transfers some money to you and if your friend clicks on it it does the reverse.

Is this what you're looking for?
