Eldar Allies for my Tau

I decided to add some Eldar allies to my Tau army, but wanted them to have a decidedly Tau feel.  So far, I have a Farseer to add some psychic power to my force and some jetbikes to zoom across the board and claim objectives.  These aren't due to be painted until early October, so they might not see any action for awhile.
