Before we get too far into the varieties of text string that can be 
used, shouldn't we try at least a small-scale user study where they 
are presented with a text string that they are already accustomed to 
having a specific use (and meaning, in context), then seeing whether 
they attempt to use it in the normal context despite it being 
presented in another? My belief is that, even with a disclaimer 
warning them that the text string which *looked* like an E-mail 
address might not necessarily *be* an E-mail address, they'd still 
expect to be able to use it as one. Which means ID's would need to 
take into account *all* naming conventions, or at least the popular 
ones, even outside the space they were normally using.
