No - Array types aren't available everywhere. However, it would be nice to be able to support them (even if not in core); if this GSoC lays the groundwork to make this possible, then it's worth looking at. I was more interested in the m2m issue - the 'natural' way to handle m2m on some NoSQL isn't to have a separate relation, it's to maintain a list/set of related references.
