Yes, the linux application will run on the
Linux-server, and its output will be visible
on the [same box] linux-NO-client.
The magic comes from, being able to cord whole
textStrings, at the client-side, which you can
pick off of intelligent menu/S, which you can
see on the same NO screen, in a different
Frame to the NO-vncFrame.

AFAIK that's about communications and
not vnc ? OTOH vnc uses TCP/IP communication,

No ! Since I'm talking about interactive
computing, the server speed is irrelevant.
It's my reduced cognitive load that counts.
As confirmed the NOclient takes over a
second to redraw the server's view, and I
expect less to update an input char, because
the whole screen in NOT updated then.

Yes that's the whole point, with multi-tasking linux.
Without standing up I can switch between:-
* 2 installations of ETH-Oberon,
which I need to colour complex text to make it
easier to grasp, and for mail & NewsGroups
* 2 V4 Oberon, which is also nice to read my
* linux pdf, ps, ..etc. viewers
* full featured browser - sometimes needed,
* fast http-fetch lynx & elinks for tables,
With a slow, expensive inet connection,
I've got to optimise.

No, and it's not advised.
Just that I didn't yet find out how to run 2
non-root X-sessions. It's not CPU time that
matters, it's user's cognitive load ?
Before I proceed, please confirm that:
* you can have a linux-Xconsole/VT running
on your vnc-server,
* which you can see in your NO-vnc-client,
* and you can input to the NO-vnc-client:
'ls -l', by MR/MMing from your NOscreen.
* and you can see the result, which the server
sends back to the client.
Perhaps you need to input the <CR> by keyboard ?
Thanks, my VNC*.Mod sizes are similar, but have
you got the 'date stamp gagdet' reading
"07.02.01 11:05:29" which you can see if you view
VNC.Mod with Desktops.OpenDoc ^ ?
Unfortunately the Linux-ETH sources are all in
one massive file and I don't even know if the
VNC*.Mod will be included until I've d/l-ed it.
For those who can't understand what all the fuss is
* linux cutNpaste [& AFAIK M$ too] is clunky
compared to NO.
* my linux editor needs a pianists operation
of <F2>, <F3>...etc., whereas NO needs no
looking at the keybrd.
* I don't want to look up to read 3486/7452
when I can better see the 'side-bar-marker'
showing that I'm about 55% into the text file.
* I don't want to have to type-in search strings,
when I could just select them....etc.
IMO the 'recognise instead of remember'
paradigm, used in NO menues...etc. is what
made the initial spreadsheets the killer-apps.
of personel computing.
Thanks for help.
