Peeking ahead in a DataObjectSet

I know it's possible to "peek" ahead or behind in a DataObjectSet. That is, look at the next or previous record without changing the iterator. What I'm wondering is, how do I use this function? What I'd like to do is when my DOSet is in a control, I need to make a decision while in the loop that depends on the next record. For instance, if the value of the next record is the same as the current record, open a new div.. otherwise, don't.

Does that make sense? And if so, is this supported?

Yeah, that looks right, but I guess I'm not sure how to use it in a template. Could it be as simple as

<% control MyDOs %>
<% control peekNext %>
<% if Value = peekPrev.Value %>
do something
<% end_if %>
<% end_control %>
