Great idea! Some questions:

- Both R and Python support strings, factors, and complex objects in a dataframe. What is NOT supported by feather?

- Feather is "not for long term data storage". Will it be standardize in a distant future?

- Do you plan to integrate it into Pandas?

Feather currently doesn't support recursive/hierarchical data structures, like lists in R. That'll be added in the future though. We'll definitely standardise in the future so you can feel confident using it in the long term.

I have no plans to integrate it with pandas, but I'm sure Wes does ;)

Will you take a storage approach for nested data similar to Parquet?

Feather doesn't support a number of pandas features (but these are features that R doesn't really support, either): https://github.com/wesm/feather/blob/master/python/README.md (not comprehensive)
