Well yeah ... but in an online banking web app, the heavy lifting is not
done by the web application ... it's done on their big iron.  I would
imagine that any NEW application that's going to use PHP on the iBox
should be carefully analyzed to determine where the various components
should run.

Of course, this isn't unique to a PHP application ... *ANY* application
should go through this analysis.

For existing applications, I'm sure a lot of the logic is being done in
the PHP ... it certianly is for the PHP applications that I'm running
(wordpress, OpenAds, etc) ... that doesn't mean new applications, that
are targeted to the iBox, will have to be that way.

I lack the information to be able to comment ... perhaps someone whith
more PHP on i experience can chime in?
