Sorry - I was on the road and had to use a web interface.  It looked OK during composition.  Is this better?

At the moment, we're trying to keep our work focused on just the core RMI4 driver.  It's evident that we've still got a bit to learn, and I'd be more comfortable keeping our learning experiences confined as they are now.

However, a general capability in SPI core is a fine idea for future work, once we get the RMI4 driver ironed out.  Can we agree to defer that for now?
