I'm in favor of a brief and coarse regex, which is suitable for 
detecting obvious junk. The above proposal looks good enough to me. I 
wouldn't mind adding an outer bounds check, e.g.: [0-9a-fA-F.:]{3,45}

If an implementer sees merit in a comprehensive syntax check, they can 
add one to their software.

Matt
