If it were me, I'd pick a day of the week, and use to_char(<date>,'D') = x (e.g., 1 for Sunday)

Ok, I'm drawing a blank here as my brain seems to hvae taken the afternoon off.
I have a dataset:
HOST_NAME TARGET_NAME SNAP_DATE TABLESPACE_SIZE
- ------------------------ -------------------
HostA Dev1 9/1/2009 99,999 HostA Dev1 9/2/2009 99,999 HostA Dev1 9/3/2009 99,999
HostA Dev2 9/1/2009 89,999 HostA Dev2 9/2/2009 89,999 HostA Dev2 9/3/2009 89,999
What I need to do is come up with a query that takes the above data and ONLY shows dates of weekly intervals. I need to get the following dataset:
HostA Dev1 9/1/2009 99,999 HostA Dev1 9/8/2009 101,999 HostA Dev2 9/1/2009 89,999 HostA Dev2 9/8/2009 91,999
I think I need to use an analytic function of some sort, but I cannot seem to come up with the syntax.
Anyone have any suggestions/thoughts? (Obviously I could create another date table as a driver table and join the dates to it, but I know there's a simpler way)
