i was under the impression that afs has always let the storedata complete
asynchronously if the file is one chunk. (maybe this is why you wanted to
know his chunk size ...) afs3.4 puts this under user control, i gather.

ugh. i guess you could proxy authenticate the pop server, but this would be a
lot of work, for marginal gain. (who wants to rewrite the world just to
support some laptops?)

yeah, but amds is a horror show to install, administer, and use.

i don't like mechanisms like khat or the reauth daemon.

but this is a pain. i like to collect new mail by popping the inc button in
my gui, not by finding a window on an upstream machine etc.
btw, i'm in the same boat as mike -- for going on five years now -- and i just
say the hell with it and inc/pop into the local cache, storing back to the
servers. oh well. maybe i've just become inured, or maybe my link is pretty
fast (19.2 zyxel + citi rx hdr compression), but i'm pretty happy with it.
still, emailed postscript (and gifs ... hehe) do tend to mess me up -- but bad!
