Totally disagree.  I use namespaces only for classes, or the temporary extending of an existing class.

In the group I work with all modules are created in object oriented fashion, without exception.  It is just too easy to not do it.  Further, to wait until there is a clear need is often too late, with too much investment in what "is" or too high of a risk for change.  I tell all developers that I work with to never assume that an object will never be used elsewhere, in fact, the opposite, assume it will be used, but do not over develop for the current needs, only implement what is currently needed.  This has reaped great benefits for our group, allowing us to create enough business infrastructure that allows for even faster development on projects that were never thought of at the time the infrastructure was put into place.
