High Latency Survival Tactics (Was: Re: Thunderbird stupid about X traffic?)

Nice meaty discussion on this topic! As Paul mentioned, cellular
data can be considered high-latency for most purposes, so this one
probably isn't going out of style any time soon.

Somebody stop me before I try running PuTTY under WINE on Linux. :)
I guess a good ancillary question is "where's the development action
on 'terminal emulators' these days?" The last big news I heard was
ctrl-shift-t in Gnome's terminal.

oh, wow, alt-x works now? I wonder how many years I've been using
esc-x since that started working... come to think of it I might have
learned esc-x on an ULTRIX terminal and never tried it on linux.....
thanks, Bill, one can never be too pedagogical here!

A few times a year I decide to write a local-editing terminal/shell
that will bulk-transfer completion data in the background, but then
something shiny distracts me from it. Somebody (Ben probably)
recently pointed out ssh's stream multiplexing feature which should
make this easier. Usually if I just wait long enough somebody else
does it. ;) I may just be impatient on this one (and definitely lazy).

sshfs might be a slightly lower overhead (human) way of accomplishing
this since your editor will likely load the file into buffer for
editing. n.b., emacs seems to have a problem with sshfs via fuse on
some OS's (MacFUSE being one currently-borked implementation with
insufficient signal handling).
