Hi all, last year in Brno, a handful of people had decent luck gathering PGP signatures by performing impromptu verification during casual hallway chats.
Of course that was only possible because both parties had come to the conference prepared, specifically carrying with them printouts of their key's information in addition to their government IDs. I suggest that we encourage more of that at this year's conference. If you are attending KVM Forum and are interested in strenghtening the PGP web of trust, prepare little paper slips with your key's details on them ahead of time and bring them to the conference; then, while you're chatting with another attendee, ask whether they'd be interested in exchanging signatures. Please speak up if you think there's any reason to discourage this practice or to avoid encouraging it. Happy signing :) -- Andrea Bolognani / Red Hat / Virtualization
