As others have said, shipping gcode to OctoPrint from S3D is ezpz and can be done with a simple file share. Because it requires expertise on the OctoPrint side, it isn't all that high value of a feature in my opinion.
But S3D folks, OctoPrint is so ubiquitous, and has a published REST interface, and a discovery "plugin" thats included and enabled by default. Simplify3D should use mDNS/avahi to detect every octoprint device on the current network, poll information from, and enumerate them. Once this is done the printers should behave exactly as if they're plugged in with USB. Ideally including a dashboard of all devices current temps, coordinates, etc. This would be a killer feature and I believe would be extremely appreciated by the community. Don't half ass it though!
