Yes and no.
Wouldn't it be nice to just "Save" the View Scheme to a file and be done with it? Unfortunately, this is where the "No" lies. Maybe version 12... It's been asked for once or twice before.
There is a roundabout way to "share" them with people who you want to help out with MC though... The View Schemes are all saved within your "library" (the data files where MC saves your database info). If you transfer the library to the other computer (again, not the actual media files, the database files) and then set up MC to use it (File --> Library --> Library Manager) then it will create all the View Schemes (and Playlists and everything) on the other computer.
Of course, all the files will be missing, but you can just Select All and delete them out of the database.
I use an automated version of method to keep my two machines' libraries in sync (so that I can tag my files on both machines, which isn't possible using the library server currently).
