In regard to boiling bottles and letting them cool in your pack...if you do boil water in the bottle, make sure the lid if off. Boiled water produces steam and that can come with HUGE pressures. Last thing you want is your lid to bust open and get sprayed by boiling water! Once the water is boiled, be careful about where you place it in your pack. If you have a poncho or something like that, the 100 degree water bottle will nicely melt that away. If next to food, it could cook it unexpectedly, and if that food is left to cool.....well, my mum always told me not to reheat rice. My advice is to let it cool properly, or wrap it in a heat retainer or blanket and enjoy some nice hot water. Could always just drop in a tea bag and let it brew up for when you next stop. Either that, or leave it to cool over night.
