Re: repacking the rice -- probably not necessary if you buy the variety of rice packaged in strong plastic bags. Typically Japanese and Korean companies package their products this way. It seems like it may work well for long-term storage. To protect the bags, you can put them in plastic bins, I guess.
Re: long-term storage -- be careful of the bags made of fiber (more typical of Indian companies). Insects can get through and breed, as I have discovered through experience.
@Conway Yee: yeah, fresh rice does taste better, but I don't particularly care about the stickiness. How fresh does your wife want it? I figure the bags advertised to contain "new crops" probably have been siting for a few months anyway...
Is rice suitable for survival scenarios? It's a staple in many cuisines. Almost no one is allergic to rice. It packs a lot of energy for its size, though the white variety has less nutrition than the brown variety. It takes time to cook, and it requires a low, steady (i.e., carefully controlled) heat source. It requires some water, but not a whole lot. But it's harder than boiling water. What are the pros and cons? Maybe we can discuss a bit.
