i second the silk sleeping bag/sheet. the bonus is that bugs can't get through it either. lasts forever. a sarong is an alternative cause it's so versatile. cover/sheet/towel/etc and it dries so quickly. i stuff one of those travel pillow cases with clothes. any way you could get an iphone? could be your phone, music, mini computer, clock, alarm, you could also upload an eguide (not sure where you're going and for how long, sorry if this is irrelevant). don't forget the lighter and most importantly the headlamp. i never leave without one...
