wow I started this thread about 18 months ago and it is still going strong. It's funny that I see it again now because I'm going backpacking next weekend for the first time in about six months and I'm scared to open up my container of Nido that I bought so long ago. I'm sure it has gone bad by now. I don't use the stuff often, but it does taste great...truly like whole milk.

I haven't had a lot of problems with "lumps" and usually just mix it in the cup...although bringing a plastic cup is an additional item that I have to put in my backpack. It doens't weigh much, but it takes up a good bit of volume. It is worth it on some trips though.
