My flow is similar to Cliffs. I use a Waiting context that is on hold (pretty much the out of the box one). If there are items that I need to do but can't do them until I get something from someone else, I create a sequential action group in the project. I place the action 'Guy to give me the whachahoosit' in the waiting context and at the top of the action group. All the stuff that I can't do till I get the whatchahoosit goes after it. It keeps the items out of my actionable lists and I think it represents the situation quite well. I am able to add other actions to the project while I'm still waiting on someone. Works well for me.
