Probably not.

The immediate problem you ran into is that by logging in remotely, you are not in the same DBus session as the running Sugar instance. That could be worked around by setting the DBUS_SESSION_BUS_ADDRESS environment variable.

But I doubt this would help you running the activity remotely. Sugar very much assumes an activity runs on the same host as the X server, that is, locally.

About the only way to run Sugar remotely is via VNC. But then, why bother? VirtualBox works fine. What is the actual problem you want to solve?
