It (finally) occurred to me that we can have our cake and eat it too in this case.

We can have the sweet deliciousness of API symmetry and retain the implementation advantages of remote iterator & collection by having both take-multiple and contents return:
Iterable.

This would introduce more flexibility in the spec, allowing more design decisions to be made by those implementing, while presenting a uniform external return type to the users. (A relatively standard one at that.)

When I was looking at the remote iterator earlier, I was thinking it would probably be best to have it implement Iterator and probably Iterable anyway.

The only potential sour note is that Iterable is a 1.5 interface. So that's come up again.

We could define our own Iterable, in one of our packages, with the same definition as java.util.Iterable.

However, it would not have the nice for-loop syntax, and we could spend a lot of time building up workarounds for not being 1.5.
