Actually, we should be pushing user agents to make long descriptions  
discoverable. The best native browser implementation of this was the "not  
all that great" iCab version, which changed the cursor. JAWS on the other  
hand manages it perfectly well for its user interaction. I don't think  
that my effort on TellMeMore is especially brilliant (nor was it intended  
to be) but it at least gives some hints at ways forward. I think SIlvia  
had some more ideas too...

I think we can confidently say that discoverability is something that  
longdesc needs to work well. Since I don't think we are in a good position  
to sput authoratively on how that discoverability should work, I don't  
think we should try to spec it much, instead looking for innovative  
implementations to show the way.

cheers
