Since I've been camped out on the EEEpc at breakfast and lunch times
lately, often in places without net, I put some trivial queuing into
hive-braindump.py - if it doesn't see net, or an attempt to
post fails, it queues up the item until next time. There's a
--flush-queue option that might be useful in a personal
net-start script.
Still haven't gotten this hooked into emacs any better than running it in shell mode; mostly that's blocked on not having found a sane way to list all tags, for a completion-table in the prompter (and without that, it's boring, running it in an existing emacs shell buffer is actually more useful.)
