Sync VM between two host machines

Does anyone know an easy and efficient way I could sync a virtualbox VM that is like 20-30GB VHD size across two computers. Say i take my laptop to school and work on the VM from their, then later at night i could launch the same VM on my desktop and work on it with the changes i made on the laptop. I know this can be done by doing a normal sync but is anything close to real time possible. You could use something like dropbox but the space you get for free is not enough for a decent size VHD.

Has anyone ever done this?
 
Are you worried about changes to your documents or the apps? For docs it's easy. Redirect your folders (Fusion does this for you) to folders outside the VM. Have those sync to like Dropbox. Just run two diff VMs on each host. That's how I do it with my iMac and my MBP.
 
Check out LinuxLive:
http://www.linuxliveusb.com/

Its purpose is to have a bootable live linux with persistence (which may not be anything you care about) but the cool thing is it lets you run whatever distro you have on there as a VM.

I would take a look at what they use there--some kind of portable version of VirtualBox.
 
Guys it looks like he wants to sync the whole VM between two machines. Real-time synchonizing is going to cost you money (most likely) or you could use Microsoft Synctoy if you wanted an off-line sync between your laptop and your desktop once you're home. The problem is going to be transferring the 30GBs of files every day.

That being said, just keep the virtual machine's files on an external USB drive and call it done. :D
 
Few things we need to know before we can give the best working solution:

1. Is it only files you care about? Or do you want software/sysconfig stuff syncd as well?
2. Do you need access to the VM even when network connection isn't available?
