No. Voldemort would never allow a mechanism that would enable one DE 
to recognise another. Remember we're talking about a secret 
organisation - for one member to potentially be able to point out ALL 
other members means that one traitor can bring down the whole 
organisation. 
At the graveyard scence, we saw how Voldemort used the mark - as a 
means to call his followers to his side. I don't remember his exact 
words, but I did get the impression that he is the only one who can 
make use of the mark.
