Syncplicity cloud storage is available anywhere you can get an internet connection. You can move a system anywhere you go and it will connect and sync your data regardless of the location you connect it.
You can connect multiple systems to your account. You log in to the Syncplicity client on each system using your same userid and password. You will be asked to provide a unique system name for each one, and then all the data is available to select for syncing on each system.
There are some helpful videos that demonstrate this and other Syncplicity functions - and tell the story better than I can in words. Take a look here and try the introductory ones, they are short and focused for new users:
