Larry,
I expect if we are all in the neighborhood of 68 to 72 gear inches there won't be any problem staying together. I may be tempted to try to suck wheel on the freewheelers, depending on the situation. I run a double sided hub with a single speed freewheel on the other side. Sometimes that is enough relief to hang with a regular group.
If there are enough fixies then I will not cross boundries.
