I had an idea. (perhaps it could be a separate thing, or a choice in the config file, to appease people who dont like the idea?) We could have advanced compressors take water from a buildcraft tank to make snow. Although, since we still need multiplayer, i suggest using buildcraft 2.2.13.
I think that all you would have to do is make the amount of water that the compressor holds bigger, and then use buildcraft API
