My 0.02€ on this:
Currently, if hotmail goes down, I can still read the emails since my
account server is gmail. From what I see, current wiab does not handle this
case, meaning that if hotwave is down, gwave won't let me read the hotwave
waves i'm a participant of. Is this correct? If so, that's the main point I
see in favour of pursuing a P2P version of WiaB from my pov. And of course,
we would get the rest of goodies of a p2p system as a bonus.
That said, I'd be wary of replacing a 300k LOC codebase with a new version,
when we are barely managing to maintain the existing code. But maybe the
current WiaB codebase is so obfuscated (from the point of view of an
average coder anyway ;-)), that a new version could be made simpler, and
therefore be able to attract an interest that current WiaB codebase is
unable to.
In any case, I wonder if making current wiab *way* more easily federable
would in practice equate to a p2p version of wiab. I.e. modify WiaB so
that, in the future, any luser can "aptitude install wiab" and have a
federated server+client of wave, that can connect to other servers without
any further configuration (or extremely little configuration at least;
think BittorrentSync levels of usability, for example). Is it technically
possible to make wiab work like a P2P network, or are federation/OT/...
protocols simply not able to scale like that?
