That's a fairly reasonable concern -- just changing it for the next
release would be pretty easy, if we decided to.  If there's a static
maximum size that would be more likely to accomodate most users, what
do you think it is?  Regardless, we need to consider the impact, as
Jonathan noted, on the size for regular membership messages and groups
state exchange messages.  Maybe, we need to find a way to remove these
