Hi Rick, Here are my thoughts, straight to the point. Some sites use Javascript. However, Lynx finds nothing. We should be more concerned that sufficient accessible text is available, not whether or not it is compatible with an old browser like Lynx.
Many pages use tables.
JFW 3.5 does a good job with tables. If a popular screen reader like JFW or Window-Eyes can handle tables fine, then I would say that those tables are accessible. Some of this responsibility must come from our end. We can't expect everyone to do more extra accessibility work than is really necessary. If screen readers exist which can handle a particular structure, than that structure is accessible, so long as it is implemented in a way that screen access software can read.
