Where it would be handy is for those odd times when one doesn't have their clipboard open and someone communicates with you in some fashion.

perhaps you need to refine your wish a bit more.
for example in middle of a furball with both range and squad vox, with names changing to fast it will be hard to accurately see who is the one asking for help. and the location given is not as accurately as if you had the clipboard open. for example grid 7,7,8 covers a lot of real state. if there's a single friendly con, not a big deal but with multiple cons on the clipboard you arent sure who it was unless you ask again. then his name will be highlighted in the clipboard. which brings up the original fix for it. if you arent sure then ask.
if somebody is calling an noe then his location is irrelevant, what is important is the location of the noe. for example I have called noe missions even though i was sectors away in another location. somebody else on squad vox mentioned and also asked to tell everybody as he was busy fighting. if it shows my location then people may get confused just like using the command .goto semp as it may send you to the wrong field.
your wish does look like a good wish. but if you really think about it, it may confused more rather than help in a lot of situations. I think it would be better if you just ask to repeat the info. I do it all the time in middle of furball when I am not sure of the location of the player asking for help. with the name highlighted I know exactly who it is.
