[Linux-Biella] ancora a proposito di quoting :D

[Matteo Peraldo]

spulciavo la posta...
cosi per controllare se ero davvero l'unico a fare post-quoting...
cosi... lo so che sono una testa di c...o
e che il discorso era chiuso... cmq quello qui sotto è un messaggio di
una mailing list di un gruppo di lavoro di IETF...
mi sembra che sia un'abitudine piuttosto diffusa la mia... e non sono
proprio dei newbie :D :D :D

I think Bamboo is certainly one to consider, but I think others are
strong contenders too. Kademlia is certainly one that has a number of
things going for it. It is used in eDonkey, so I think it is as well
established (maybe more so) than Bamboo. (Not that there is anything
wrong with Bamboo, either).

I think we should also consider implementation ease when choosing one.
Has anyone here implemented both? Any thoughts?
