RE: date pickers

Drawing the line is the tricky bit, but it is something we face with
every ALT attribute.   I think the real-world choice is between:  (1) a
text entry box next to a mouse-oriented pop-up, and (2) a table
implementation that does not included the option for direct text entry.
I would like to suggest that one of us crafts sufficient techniques and
we see if there is group consensus for some of the less-than-perfect
solutions.
