Let me reiterate.  I want my name to be visible and I want *people* to
be able to find out my email (even in a quick cut-and-paste-able way)
but I want to put up something in the way of crawlers that are
specifically out there to grab email addresses.

Therefore, making myself invisible is not an option, but I still want
spam protection.

My assumption is that spam crawlers are looking for pages containing
lots of easily parsable email addresses (recognizable by either
mailto: or just the '@' sign) and will not bother to craw the entire
web -- too expensive -- nor will they bother to write bots that do
intelligent searching for "hidden" email addresses.  They will use
other web crawlers to find publicly available mailing lists though.

The Findmail solution is the right way to go, I think.  See
