[ale] Multiple KVM switches?

[Christopher Bergeron]

Guys - I have dual monitors and I had an idea and thought I'd run past 
you guys.

I was thinking about using 2 different KVM switches, and connecting each 
monitor output (on the video card, a matrox g450) to a separate KVM.  
The net result is to have 4 machines (4 port KVM) and 2 monitors all 
[monitor] switchable independently.  The keyboard and mouse would be 
tied to the first KVM continuously.

Let me elaborate:

I have a linksys KVM that controls monitor #1 and keyboard/mouse.  I can 
"toggle" through my first monitor/keyboard/mouse using the CTRL keys 
(double click).  Here's what I want to try doing.  By using a different 
KVM that changes screens using a DIFFERENT key sequence (ALT would be 
perfect).  By connecting my Primary monitor output to one of the KVM's 
and connecting my Secondary monitor output to a different KVM, I should 
in theory be able to switch which monitor is displaying what.

This is tricky to explain.

Can anyone recommend a KVM that switches using a keystroke other than CTRL?

Does anyone think this won't work?

Should I send a diagram?

Is there a better way to do this?  I use multiple operating systems, so 
I'm pretty much tied to a hardware solution here.

Any insight is appreciated.

Kind regards,
CB
