I don't see how this could matter. Lion stores all of the data for its autosave/versioning features (an SQLite database, incremental file changes, previous versions, etc) in a hidden directory located in the top level directory of the relevant volume, not in the working directory in which you are storing your documents and which, presumably, you are syncing with Dropbox. AFAICS the new document model leaves the structure of your working directories untouched. (Perhaps there are differences in the .DS_Store files between Lion and SL, but Dropbox doesn't sync those by default anyway.)

But I have (almost all) my files in sync with two other machines through Dropbox, to my entire satisfaction till now (after overcoming initial problems with file encoding, but this is another issue), and these other machines are still using Snow Leopard (last version).

Does Snow Leopard understand Lion's document model ? Should I expect conflicts, missing versions of a file, etc.? Will the "hidden" Lion old versions of a file be invisible to Snow Leopard ? Should I wait until I am able to upgrade the two older machines to Lion ?
