Of course, if you want to see the actual machine, an IP camera is a reasonable way of doing that.
EMC has been designed from the start to allow multiple user interfaces, which can be on a remote machine if you like. This is in addition to the option of running a remote X session, or remote desktop software such as VNC. The NML messaging system allows you to set up channels as being remote. I believe there are sample server.nml and client.nml files in the sample configs directory (maybe in common/ or something). You can run AXIS on the EMC machine and start a program running. When you get to work or wherever, fire up Axis, tkEMC, mini, emcrsh - whatever, and if the NML file is configured correctly, you will connect to the remote machine. Both UIs will be running, and either could take control - if someone at home smells smoke and hits ESC on that keyboard, the machine will stop. You will see the change in machine state on your remote UI. Similarly, you can hit ESC to stop the machine, and the UI on the PC controlling the machine will show what you have done. There are a couple of caveats to this: 1) I'm pretty sure that nothing bad happens, but you should experiment with running a part and then starting another UI. Specifically, try AXIS - I don't know whether it will happily connect to a running EMC or if it will load its "splash file" and stop the machine. 2) Specific to AXIS, you would need a command-line option to disable the creation of HAL pins on the remote control PC. That machine isn't likely to (and doesn't need to) run an RT kernel, and besides you don't want HAL running on your machine at work, since it's not connected to the machine anyway. 3) File handling is a little weird with remote machines. You need to have the loaded file available at the same path on all machines you want to run UIs on. NML doesn't transfer the file, and the status buffer has the full path name to the file, so if you want to see the code as it's executing, you'll need to make sure you have the same file in the same location on the remote PC. Remote X is an option, but it's probably not the best in the case you're talking about. You could remote into the box and run another UI "locally", you'd just see the window on the remote workstation. This is equivalent to running two UIs on the same PC at the same time, so if you experiment with that on the EMC machine, it's the same as far as EMC is concerned when you access the UI from work. VNC is the heaviest protocol for this, but has the advantage of running only one instance of the UI, and also requiring no configuration of EMC.
