HOWTO: Running gnunet-service-transport under gdb.

I needed to run gnunet-service-transport and set a breakpoint at __longjmp, here's how I did it.

Polled GNUnet Chat

This is a proposed protocol for implementing a chat system in GNUnet. It is polled, meaning that clients ask (poll) the network for new messages to a specific room. It is much like the protocol for anonymously searching for files on GNUnet. The protocol prevents eavesdropping by making the participants in the chat room aware of being polled and from whom the poll originated.

Motivation
==========
The reason to design a polled chat system is to exploit the success and well-understood behavior of the file sharing protocol.

IPv6 back for gnunet.org --- just in time for IPv6 day

IPv6 ready

gnunet.org is now again reachable via IPv6 (at 2001:4ca0:2001:42:230:48ff:febb:4bca) --- as it should be for the first P2P network that fully supports IPv6 (we've had partial support since about 2002).
