I listened to Manu Sporny the other day (re: web payments!), and now by coincidence I ended up on this post (I was trying to login to WIFO with Persona, ran into trouble and was going to write on https://d.wifo.org/t/login-methods-available/12 that something seems wrong, but then I successfully logged in through another less plugin-ridden browser instance).

What I actually want to say is, hey, this sounds interesting, I should have a look at some point. :-)
