Yes, there are still water beds in the world. They are not as popular as they once were.

Water is pumped into underground salt beds as a method of storing excess water during periods of high supply or low demand. The salt beds act as natural reservoirs, allowing the water to be stored until needed. Additionally, the salt beds can help prevent water from being lost through evaporation or seepage.
You can be shipped in a box as long as it is waterproof and when you in the box you have sufficient oxygen food and water to get to your desired location.
Not commonly, no. Purchasing water beds made for cows can be pricey, depending on availability which depends on location of the farm, regionally speaking. In North America, most farms just use straw or sawdust bedding for cows to lay on, as its cheaper and easier to clean than with water beds. Note that consideration of the purchase of water beds is only for dairy operations, not beef.
Yes, you are never required to use a frame except for water beds.
