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 ;)
As one of many people flicking between R and python/pandas, do you feel there are other areas that have the potential for collaborative tools between the two communities?
In discussing Apache Arrow in the context of Python and R, we wanted to see if we could use the insights from feather to design a very fast file format for storing data frames that could be used by both languages. Thus, the Feather format was born.
Is the feather in insights from feather the right word? It reads awkwardly to me, which could just be me lacking context.
