One of the nice things about MySQL PS, is that there is no pressure on us at all to "upsell", to pitch additional products and services to our clients for the purpose of adding to our bottom line.
One of the big fears with being bought by Sun is that Sun will start "encouraging" us to start pushing Sun's hardware and proprietary software, but that threat has not yet materialized.
On the other hand, on the last 3 gigs, I have sold a handful of copies of High Performance MySQL, and probably three tickets to the O'Reilly MySQL Conference.
Maybe O'Reilly should be paying me a kickback. :)
