If you want to use X.IO to stream standalone, you will be able to do this officially through your OTOY/ORC account right from desktop.otoy.com. You can test it right now, and use your dropbox or gdrive account to load your projects or ORBX files right into Octane.
We will be updating this build to V3 as soon as 3.03/4 is final, with support for ORC - so you can actually use Octane+ORC entirely from the web. We will the see if we can update Blender on desktop.otoy.com with direct support for the Octane plug-in baked in. This would give you another option for authoring on the web desktop beyond just SE.
