You could set up Dropbox, Google Drive or similar to sync them (assuming you can access such services at your office).
You may need to move the ADE libraries to another location (eg maybe from Documents/My Digital Editions to Dropbox/My Digital Editions)
and then make a directory junction so it can also be seen by ADE as in its original location.
eg on an Admin command line
mklink /d "%userprofile%\documents\My Digital Editions" "%userprofile%\dropbox\My Digital Editions"
Thanks for your kind reply.
It is a good idea.
