Hi and thanks for ideas!Google Drive or Dropbox are possibilities. Version control probably isn't an issue with one person coding, or my wife coding totally different stuff. Usually.
Dropbox at least keeps a physical copy on all machines, so things work fine if the net is down/slow.
Where/how do I tell the IDE that stuff is not In The Usual Place??
Rob, in my 'standard' installation terry/arduino contains terry/arduino/libraries so I THINK I only have to tell IDE where the /arduino root is??
Google Drive also keeps things physically on your machines, just like DropBox.
To change Sketchbook location, go to File > Preferences from within IDE.
Versioning sounds like a good idea. I may well look into Subversion and SVN to see if it can be run on Windows.
