Which end?  I'll assume you mean _not_ the server end. :-)

The MAC address for the client end (i.e. the end you don't control) 
isn't going to be available to you unless it's local to your network. 
If that's the case, one option is parsing the output of the "arp" 
command as appropriate for your platform (note: this is inherently a 
platform-specific issue).

If the other end is not local, it's unclear what value the MAC address 
would have for you.  Maybe describing that will lead to some more 
effective solutions being suggested.
