Just want to say that I'm very enthusiastic about this!

Like @lamorton, I also find myself having a lot of variables with names containing the name(s) of their "group(s)".

My initial idea was also to keep flat datasets and add some logic to get/set groups, but it wasn't very clear and well explained.

One important reason to keep the tree-like structure within a dataset is that it provides some assurance to the recipient of the dataset that all the variables 'belong' in the same coordinate space.

Makes perfect sense!

I also find the idea of using tuples very clever! @shoyer do you have an idea on how it would work with serialization to netCDF? We would also have to decide how to display groups in the repr of the flat dataset...

@lamorton @shoyer unless you want to open a PR, I'd be willing to start working on this.
