Heh, I'm back on the customer side of the fence again for this gig
We have VSC in place in a test setup. My experience has been that it frequently runs into what appear to be random java errors, usually right when one of the more junior guys needs to do something simple. What I liked about the Host services stuff was it was reliable...I never had a report of anything not doing what it was supposed to do.
With the horrible state of Java right now, in the name of security it's damn near impossible to get anything java-based working consistently, I'm trying to avoid such solutions.
I'm hoping that either Host services will be available for cDOT Oncommand setups soon, but now that the latest release is a virtual appliance I'm not sure what the direction is. Thought it might have something to do with the Workflow Automation tool.
