I'm not suggestion the ALTHREF - or MIRROR - tag shouldn't be included; 
this is under the condition that the client can get the document _in 
the first place_.

What I actually said was both a suggestion of a META element (it would 
be in the upper-most section of the page so so have the highest chance 
of being downloaded, afterall) and for a secondary mechanism in case 
the HTTP server could deliver a single sausage of information; which of 
course is reliant on the secondary workings *not* relying on the http 
server!!!
