One comment -- I've often seen this mentioned as a way to obfuscate
email addresses, but I would think that it's fairly trivial for address 
harvesting programs spidering the web to be able to de-obfuscate such
addresses and that they're likely already doing so.  In Perl, one can 
simply do something like

    $text =~ s/&#(\d{1,3});/chr($1)/e;

to convert the &#... sequences back into 'mailto:...' before scanning
the text for potential vict.. er, addresses.
