I we assume that two people are always in each others buddy list a
person who comes online can look up all his buddies on the DHT and send
them a direct notification that he is online. Except for some
complications when both parties are firewalled (which would require a
solution anyway if you want to do anything useful) I see no problems
with this approach. Am I missing something?
