I know this would be a bit of a can of worms, when it comes to cross-platform compatibility but I am frequently finding myself going between systems, namely because I have different equipment on different setups, e.g., for recording and mixing but one thing never changes, that is Audio files.
In this day and age, I would want to be able to assume that I could simply use some kind of intermediary, to be able to syncrhronise files, while not having to resort to the Sneaker net, as we have since, it must be; when floppy discs arrived and now the only difference is, it is a thumb drive or whatever portable storage so please SB, rather than make me wonder as to whether I should set up a file server and whether that would actually work (I could ask a question), how about having some way of checking files on instancing of a project.
Cheers
