OTR leaves that up to the underlying IM network.  OTR assumes the
network already provides in-order delivery (doing IM when messages can
get reordered seems like something no IM provider would allow), but
allows for messages to be dropped (one party goes offline, messages are
dropped, etc.).

I don't think guaranteed delivery is even something we *want*, since if
your buddy is offline, that would imply there's a long-lived decryption
key somewhere, and that's defninitely undesirable.
