I'm using a snom 200 v2.03o with two extns defined, and the lights work
as expected. (They didn't on some earlier version though.)
Make sure to define the two (or more) buttons in web interface under
Key Mappings (P1 = Line = Number <sip:3002 at its-ip-address>, P2 = ...),
matching Settings, SIP, Lines registered Account numbers.

If I press extn button #2 and place a call, the callerid properly indicates
the correct extension. If I call the extn number assigned to button #2,
the LED correctly flashes indicating an incoming call. When the call is
complete, all LEDs are off.

Regarding your key system question, I've never heard of anyone with a
configuration that would actual light button #2's LED if some remote
sip phone happened to be on the extension number assigned to that key.
If you could dream up a way to do that, it would be dependent on the
exact sip phone that you're using. There are no sip standards for
turning on/off LED's like that other then the MWI.

Regarding the traveling technician, certainly would not be all that difficult
to configure a dialplan that would provide that function. If the technician's
real extn was 1111, have the technician dial a special extn from where ever
he happens to be (maybe x2111), and the code for that extension in the
dialplan implements a staight call forward to whatever the callerid happened 
to be for that call. (There's probably a dozen different ways to do that.
Check the wiki and goggle for examples.) Dialing x2111 again when he's
ready to leave that desk could also toggle the call forwarding off again.
