Bump also would like to know.

Weird, I have been able to get curves into Maya without an issue, prior to Maya2016 I would use HDF5 but now 2016 supports ogwawa without any issues. Also not sure how it would work with Arnold, but Nvidia realesed a new version of its mental ray Alembic impoter, but it does give you geo in the viewport.

In regards to this, I can now successfully export curves to Maya and it's all fine, however I was wanting to render those curves (as rain) using Renderman (which can render curves as geo). But the problem with that is I can't seem to turn them into RiCurves in bulk (there are 20K curves) so it would take forever doing it one by one.

I will be giving Arnold a go as I have found a way to export the rain as alembic geo. I have run into a few problems in Renderman for rendering the rain geometry that I hope Arnold can address.

For some reason the rainfall which is now basically thousands of polygon “lines” (extruded from houdini curves) isn't being picked up, and the water shader I have on Renderman isn't behaving how I had imagined. I don't know yet if it's a geometry problem or how Renderman handles it so I will see if it's any different in Arnold and go from there.

Those are some interesting info's guys, thanks for that. I will check it out!
