A couple of things to consider here (if i'm understanding your goals
correctly):

- Unison is a utility that uses the rsync algorithm to do bi-directional
sync.  This means that you don't have to manage the bidirectional rsync
options yourself, but just run Unison every time either side changes.

- You can get GNOME to run a custom command on insertion of different
media types using System->Preferences->Removable Drives and Media.  I
use this to sync my digital camera cards by getting it to run a script
which syncs the files (unidirectionally, in this case), then umount the
SD card.  Then there's no need to run a daemon or poll a driver.  A
possible down side to this is that you need to be logged in.
