JamesBarr,
I thought you raised some very valid questions. I'm not sure why Def thought the insurance issue was not for public consumption but I would like to know what you found out.
Ib does not sweep cash deposits to a MM fund but instead pays interest on them. In effect, it is a very cheap way for them to fund overnight cash needs at MM rates, which are no doubt much lower than IB would pay a bank. I'm not suggesting there is anything wrong with the practice, Preferred does it too, but obviously IB is not as solid a credit as a MM fund. Thus the insurance issue is very important if one has an account greater than SIPC insures.
