The simplest way would be to synchronize your UID across all your installed operating systems. If your UID is, let's say, 1000 on every system, and the files on the partition are owned by user 1000, then user 1000 (you) will have ownership of the files whenever you mount the partition. If that's not an option, then you'll need to use Unix permissions. If you can synchronize a *group* GID across all OSes, then you can just make the files and directories group-writable by that group. Otherwise, you'll have to make everything world-writable.
