coolbutuseless, 
#RStats Help needed!
I want to email R-devel & get clarification on "Can we create custom connections in packages?"
I find the situation confusing because using the "Connections.h" is mentioned in R-exts manual - and so formally(?) part of the API
But this conflicts with the NOTE generated if you try to use "R_new_custom_connection()" which says it is "non-API"
Am I tilting at windmills? Poking the bear? HELP!
