<p>Use case:</p>

<ol>
<li>A does something on his box and gots stuck. He asks B (remote) for support.</li>
<li>B logs into the session of A, sees all windows, A was seeing and is able to manipulate the GUI.</li>
</ol>

<p>If A uses Windows it is very convenient to log into a running session e.g. via VNC. But if A uses Linux, AFAIK, this is not possible. Using VNC requires a "vncserver"-session, which is a separate session. You could get screen captures from remote by querying the X-server, but you cannot press buttons on the screen.</p>

<p>Is there some workaround for this?</p>

Actually, I revise my statement...
in IE7
, you
CAN
do some scaling.
```
```
<div style="zoom:5;font-size:20%;overflow-x:auto;">
  Hello World!       Hello World!       Hello World!       Hello World!       Hello World!       Hello World!       Hello World!
</div>
```
```
zoom tells IE to scale up the contents by 500%, and I've set the font-size to be 1/5 of normal (thus remain the same)... this scales the scrollbars (but it looks a bit ugly at this zoom, since the images are raster based, not vector based.
