I intend to run some of my World Machine workloads in an AWS instance (AWS has instances with far more processors and memory than I could ever afford, so I want to use them to run my builds faster). However, I am apparently only able to use World Machine in a single computer at any given time. So, at any time my workloads are running I am unable to continue working on my terrain.
Maybe not even the full editor is needed: just a command line tool. Actually it would be better if it was a command line tool, as it would be easier to port to Linux as well which would allow people to use cheaper cloud instances.
