aloha!

2 points: 

1) it would be useful to provide an author-centric solution -- use of 
a "role" attribute, as discussed in:

http://esw.w3.org/topic/PF/XTech/HTML5/RoleAttribute

so that role values can be used as machine parseable indicators which 
can, in turn, can be the basis for user customization of web apps and 
assistive technologies, by functioning as switches or hooks that do 
NOT interfere with the use of @summary for human-parseable information...

this is VERY much akin to the @alt imbroglio -- the value defined for 
@alt needs to be human parseable; machine processing instructions should
be derived from a dedicated attribute, to wit, role.

2) where are all the pointers to the spurious use of summary to which 
opponents of summary keep referring?  i have yet to encounter the use 
of a summary attribute that was "harmful" -- please do not make sweeping
generalizations, but provide specifics as to how use of summary is harmful
and how it has been "abused" in the past -- i simply haven't encountered
the evidence, but i have navigated innumerable documents with multiple 
tables, and can attest that without unique summary values for each table,
it increases the time it takes to parse the page mentally, for one is 
forced to discern the relationships expressed by the table for oneself in 
the absence of summary (properly used) -- something which sighted users
take for granted -- when a sighted user looks at a table, their brain 
discerns the pattern and relationship between the data sets contained in 
the table; when one is blind or one's vision is severely limited, there
is no means of achieving such a gestalt view, save through the use of
the summary element for TABLE
