Just remembered one more thing- I found a cool collapsible silicone funnel on eBay that looks to be perfect for this rig. My plan is to place the pot lid in the bottom of the bag with the pot on top; I'll put the silicone funnel in the bottom of the pot with the water bottle on top of it inside the pot. A couple zip-locks with coffee filters around the bottle should keep it from rattling and give you a very nice sediment filter.
