You need some kind of file syncing program like DropBox or Adobe Cloud so all your source files are available at both locations, then you need a VPN to access your office computer remotely. The availability of a virtual private network depends on the ID department at work. Many do not allow remote access, some do.
Once the files are in sync you can set up either the AME or the Render Cue from home and let your office machine run. AME works with a watch folder which will automatically render DI's that you place there. Other than that, there is no automatic way do it that I know of without a VPN.
Thanks Rick. Watch folder seems to be perfect. But, well - that's gonna need some time for me to setup something like a VPN But i will definitely try it out asap.
