To look at it another way.

Lynx allows the user to move from link to link, whether or not they are
separated by anything. It also allows the user to view the links, one per
line. This should enable pretty much anything to cope.

Explorer and Netscape (on most platforms) allow you to tab through links,
again regardless of whether they have separating characters.

So I would suggest that in the future we should ask for sepaaration of links,
since it is important, but that the separation only needs to be clear. For
example, visually they should be seperated, for example by ckear space.

At a techniques level, it can be argued that clear space can in fact be a
part of the link, so long as there is an obvious part that is a link. For
example in an image map it may be the case that an image is entirely divided
into a dozen links. If the image is a series of words, spaced as if a phrase,
and which make sense as a phrase, it is not immediately clear how to separate
the links. This is worse if some of the links are larger than others. But if
each link has extra space around it they are separated.

The issue applies to motor and cognitive disabilities. Sadly, I don't have
any usability data on the seriousness of the effect, which makes it difficult
to determine the priority of the requirement.

  That's unfortunate, because I had been going to extra trouble to
  separate active links with non-active non-blank characters just like
  that, as a result of an earlier accessibility recommendation :-}
  
  While I guess we'll all agree that this business is built on
  compromise, I'm now wondering whether the optimal compromise may have
  shifted...?
