Follow-up question: Linux gets frozen and you don't have physical access, what do you do?

Answering my own question: http://en.wikipedia.org/wiki/Magic_SysRq_key#Alternate_ways_...

Thanks! I didn't know about this. I'll update my post as soon as I catch some time. If you want, leave me my your twitter username, so I can mention you :)

Wikipedia tells me you don't need to hold Ctrl. Just Alt+Print Screen. I just tested it in a VM and it works. Should make it a bit easier.

And I have to say, at first i thought this was a trolling attempt to get us to try to push this sequence. But that's a really cool feature - I didn't know about - even after using Linux for years.

Thanks for the update. For years I use this with Ctrl, never got a thought to try without.

Btw, on the wiki page I mentioned is also written that: Under graphical environments (such as GNOME or KDE) 'Alt'+'PrintScrn/SysRq'+key combination generally only leads to a screenshot being dumped. To avoid this Print Screen feature the magic SysRq combination should include the Ctrl, becoming 'Ctrl'+'Alt'+'SysRq'+key.

So I guess it depends from the environment.

Oh that one I didn't see, thanks. However, it makes me wonder why Gnome/KDE can "hijack" this key combination. I mean it is a bit strange for a userland application to be able to intercept kernel level features.
