I did mention there were open-source implementations that could interface with it. I tested it against empathy (telepathy based) today and was pleasantly surprised with how well it worked. Previous attempts weren't as successful. I tried with both clients inside the same NAT though so I don't know if the firewall punching bits are as good. Thanks for the clarification on the standards, it seems to have evolved since the early days.
