Yes - since the Blender plug-in is IP based, it could work.
Without much effort, you can also run Blender (or any other Windows/Linux) app on the OTOY G2 cloud server directly, and eventually plug-ins included. For this launch, we've re already re-factored Octane SA to boot up automatically inside the AMIs without an individual license - it is usage based. This is something we will do for plug-ins next. With Autodesk applications working inside the Octane AMI, it is technically possible to get usage based plug-ins for Max, Maya, Revit and Inventor up and running.
For users who are not AWS devs, we are setting up the Octane Cloud service (which is built on the same AMIs in the marketplace). It includes fully licensed version of Windows and a turn key service for remote workstation based around the Octane Render pipeline.
