Chad,
It all depends on what I need.
First of all, I don't encapsulate them in a pseudo-object. You
generally don't need all objects in all cases, so putting them all in a
single object just adds overhead.
I also don't use globals. It makes maintenance and troubleshooting harder.
Generally I will pass the objects in the constructor, a member function
or a setter function. For objects which are more global (i.e. a
database object which may be used by several classes) I might create a
singleton (google for it).
