Hi Garth!
I'm not sure if this really solves the problem. I mean if we start "stretching"
the current layouts, things might look very bad (even in 1:1). So I would not
do that, even if its easy to realize as a starting point.
As already mentioned, I'd rather use the old skins for the look of the knobs
and so on, and make something new for the arrangement.
What do others think about that?

Throughout its 18-year history, RSA Conference consistently attracts the
world's best and brightest in the field, creating opportunities for Conference
attendees to learn about information security's most important issues through
interactions with peers, luminaries and emerging and established companies.
