OK... are there any good ideas how to mitigate the latency effect ([1]) ?

[1]=Long on my wishlist is something like a SSH3 protocol which
somehow can rival Kerberised rsh (yes, yes, I know, it's comparing
apples with pears) in connection setup latency and better handles
socket/pipe buffer boundaries (sort of |SOCK_SEQPACKET|-style) ...
(But this is now going waaaay off-topic from the original subject...
so either drop or rename subject of the thread...)
