What? Aren't they? I was serious... I don't know about a 600 F/4 but My 300 2.8IS is. Shouldn't weather sealing at least provide some type of protection?

Only when attached to a weather-sealed camera. This lens became detached. Read it again.
Not very, I'd say. I know that lots of folks use theirs in the rain. Personally I put away the 500 when the first drop falls. I'd rather err on the side of caution.
I read that.... So the sealing is only on the lens mount not within the lens itself (elements)? And is it still sealed then if an extender is attached? I have mine with the 2x a lot lately on a 1 series.. But I didn't know that the sealing is only at the mount.

As Greg said, the weather resistance is not even relevant here.
The lens was submerged in a lake, for an extended period of time. That is not even close to what a few droplets of rain do. It is much easier to prevent a few droplets from entering a lens than keeping the lens dry while completely submerged during hours. If you are not convinced, then I may suggest you look at the design (and price) of underwater housings or Nikonos cameras (in fact these are even better engieneered, since they are also supposed to resist pressure, corresponding to, say -20m).
By the way, we should not focus on the bad part and notice the bright side of things: ok, the lens did die due to submersion in water, but at least it was not eaten by the 'gators.

Could you please tell us what monopod head & monopod the renter was using? Also, could the renter tell you how the head failed? It would be good for all of us to know what the limitations are and what not to do.

To tell you the truth, we never got the guy's monopod brand. However, when we got the lens back, we saw the culprit. It was attached to the monopod by a tiny screw and that's what broke off and was still left in the tripod collar of the 600 when we got it back.
Canon says its not possible to recover.... but think this way, would you pay $7.200 for a lens that could be mounted with a first element thats was hanging around with crocs or gators ?? ( i don't care what it was!).

Isn't this always true? I mean, the choices are 1/4" or 3/8", right? I worry about it sometimes, but what's the alternative?

As I recall, the MkII converters are weather-sealed, while the MkI's are not. And no, the sealing is not only at the mount; that would be kind of pointless.

if i read it correctly, there was not a clamp attached to the foot of the lens and that little screw was asked to carry the weight , loading , and stresses of a very heavy lens
That is how all are attached just the one screw at the top of the monopod or tripod. The ball, wimberley, rrs or any other is attached at the point, the weak link.
