SPI slave mode? SD cloud?

As an excellent plugin replacement for a data logger SD. Without a SPI slave mode even with the simplest of poll sleep waits returns string methods, who how do?

The imp can’t work as an SD card I’m afraid. The best approach would be to connect the imp directly to the sensors involved and not use the logger hardware in the middle.

The logger may also not be able to supply suitable power for the imp card.
