I've been using this for the last 6 months or so. Seems pretty good as a client. Stable on the comms side, although short of an audit, I'm just having faith in the security side of things.<p>What it really needs is some way of having a roaming profile though. Currently you have to have multiple accounts, one for each device. So my friends list has a lot of duplicates depending on whether they're on their work computer, at home, on their phone, etc...<p>I'm not actually that fussed about the encryption side of things. I'm far more happy with the lack of reliance on centralised servers. You don't need an account somewhere to get it up and running, you just send a message to a friend and compare secrets to authenticate.
