Will this be available for standard R, or is this a proprietary Revolution R package?

RevoScaleR is part of Revolution R Enterprise, available to paying commercial subscribers (and free to academia).

Is it possible to get a copy of the AirlineData87to08 (in a standard format, say CSV) so we can try the equivalent examples on standard R to get a feel for how bad it would be with one of the usual packages?

Oh, Google is my friend and I guess it is this data set you are using:

A very interesting post, and white paper describing the big data capabilities.

It would be interesting to see how the rxCrostabs and rxDataStepXdf compare to the 'proc freq' and 'data steps' in SAS. Your system can beat SAS on price and also maybe on performance in manipulating big data sets.

The white paper describes the fitting of a linear and logistic regression with these huge sets. That is impressive, but would you really need millions of rows to estimate 5 to 10 model coefficients...?

Any plans to do a Mac port for Revolution R Enterprise?

I would love to see a Mac port for the Revolution R Enterprise addition as well.
