Much of it should work okay -- e.g. seeing as uploaded files are stored as blobs in the database, so should be accessible by all tomcat instances. 

Harry can correct me if I'm wrong -- but I think that one place where this might not work is in the handshaking between Dryad and TreeBASE: files get pushed at one time point while the user is logged into Dryad, an email with a link to TreeBASE is issued, then at a later point the user follows the email link and the delivered file is unpacked and parked into the user's TreeBASE account. So there might be a problem with files pushed from Dryad winding up in the directory of a different instance from what the user later uses to try to retrieve it.
