I picked up one of these over lunch, from the coffee roaster downstairs at St. Lawrence Market:

Should be just the ticket on tour but it can only do about 4 ounces at a time, so I may have to do double portions in the morning if theres someone else who is thirsty. I was considering one of the 4 cup traditional style pots but they were quite a bit bigger and heavier. It would be ideal if I could adapt the top on this one to one of the bigger pots... Maybe I will try later on.

I also picked up two of those vaccuum cups on offhoff's suggestion. They seem nice so far, but aren't quite durable enough to take camping with me. Anyone know where I could get some stainless steel 2-3 ounce cups? preferably ones that fit into eachother?
