Oh jeez, no! Summaries are wonderful and though a couple points were weird,
that is by no means a "dumb" post! I don't feel it was noise either!

etherx (or rather, the JabberBox protocol) is reliable. Future protocols may
not be. Though, code wise, we're treating the system as "reliable", this may
not always be the case.

The abstraction layer you want is, etherx! (*x) Currently transports connect
via TCP/IP, however in 0.7 a form of IPC is being used to remove the network
communication aspect.

The "solution" idea proposed was just to have everyone run with UTC and thus
not worry about passed TZ information.

You summarized, and I was a bit harsh. Large numbers of useless (julian?)
posts are painful for me.

Don't! You contribute, and contribute well! As a team, we need more people
like you.
