It's got some interesting implications if it's: domain.exe ... 'did
you mean to go to domain.exe or execute domain.exe or display
domain.pdf ?' the UI folks will have a headache with that I bet... I
could see a rule set (simplified) like:
1) if -f domain.exe && -x domain.exe ; then exec(domain.exe)
2) if ! -f domain.exe ; then openlocation(domain.exe)
that would be fun in the world of site-finder, eh? I wonder what word
or excel or '$application' does with a random blob of html foo shoved
down it's throat??
Is it still the case that folks thinking about site-finder believe
'all the world is a web-browser' ??? Seriously?

and here I took the 'bar.mime-type' to be: domain.exe or domain.mp3 or
domain.pdf ... Barry, which do you mean? (or which did Eric mean)
