title: Binding to something other than ToString: how?
body: <p>I wasn't very happy with the default <code>ToString()</code> output from the <a href="http://msdn.microsoft.com/en-us/library/system.net.networkinformation.physicaladdress.aspx" rel="nofollow">PhysicalAddress</a> class in the <code>System.Net.NetworkInformation</code> namespace. The output is formatted like "AABBCCDDEEFF",
  so I wrote an extension method <code>ToDelimitedString()</code> that returns it formatted like "AA-BB-CC-DD-FF".</p>
  
  <p>So far, so good. Now I want to display this in my WPF application through the use of databinding, but this is where the road stops for me. I don't really know how to bind to anything other than the default <code>ToString()</code> on object instances.</p>
  
  <p>Someone please point me in the right direction, I'm having terrible difficulty in understanding the msdn documentation.</p>
