You can jointly store iterators to different containers, no problem with 
that.
You only have to be careful not to mix them: for instance, if it1 was 
obtained
from obj1, you can't use it1 with obj2.

No. This comparison is only legal if obj1 is the same as obj2. 
Otherwise, you
are not even guaranteed that the comparison is defined :( as far as my
understanding of the standard goes.
