I, too, am looking to move from 1Password. Really tired of them...
I see that Multiple open vaults will (hopefully) be available in Version 6. Will that also include Shared Vaults? This is a required feature for my wife and I. We have a few internet accounts that we share and like to keep them in a shared vault that is synced.
Also, how can I go about getting on the Beta when it is released in May? If I can see some progress in the Beta, I am willing to pay for your solution at that point.
