>I have used 4x simultaneous monitors on my MBP

What do you use for that?

Displaylink x2 + 1 MiniDP + laptop screen

I run two older versions of this evga product (as my monitors are older - 1650x1080). http://www.amazon.com/EVGA-100-U2-UV19-TR-Supporting-2048x11...

Right? Unless I'm missing something, my friends and I all use a hot corner to activate the Screen Off to be able to lock our screens when we leave our laptops since there is no Win+L or Lock equivalent. :/ I guess they just expect me to close it everytime I leave? I have lots of long running stuff that I normally don't want to stop just because I want to go to the kitchen or bathroom.

Actually, that's now resolved since Snow Leopard - there's a "sleep display" key-combo (IIRC: Ctrl-Shift-Eject) that, combined with screensaver password will do effectively Win+L.

My major issue is that sometimes it showed content before screen is unlocked (likely my displaylink device) or fails to unlock (sleep/unsleep resolves this)

I don't remember if it has to be configured, but I just press Ctrl-Shift-Eject to lock my screen.

There's no eject button on Macbook Airs

Hit the power button. It pops up a modal with restart, sleep, shut down and cancel.

It's like no one read my post. I specifically do not want to sleep.

the sleeping is only for the monitors, the computer is still running.

That's... not true.

cmd + alt + eject is the sleep you're thinking about. ctrl + shift + eject is just for the displays :)

You can go into the Keyboard system preferences and set a keyboard shortcut for "Sleep".
