...

The OP's profile at Google suggests they have
made previous posts along the same lines (about
the tech. talks) over the last year.  The posts
seem to be well targeted (e.g. on-topic to the
particular group posted).

I cannot say whether they work for Sun.  Though
I do note that the only two people I know of that
do(/did) work) for Sun and post(/posted) here,
made no specific mention of the connection.
Those people were concentrating on specific
technical discussions only - no announcements.

Seems so.  They have a 'rolling topic list',
and I am guessing they 'prod and poke'
departments to free some of their tech. folks
specially for them.

I saw the answers to one such tech. talk
(related to JWS) that was invaluable, and
covered things documented nowhere else (that
I can find).

I will be interested to hear the OP's answer
to your question.
