European Hornet v Common Wasp

Observed: 24th August 2012 By: frodshammarshbi...
European Hornets nest. WSM

I discovered in a partially submerged pine tree an active nest of a European Hornet with in excess of 100 coming in and out constantly. On the reverse side of the tree was an active nest of a Common Wasp in an old woodpeckers nesting hole. My question is obviously these two species can co-exist but what relationship do and can they both benefit from this. Would the Hornets consider the wasps an potential threat and visa versa?
Hope you can give me some answers to my questions?

Apparently Not...

Wasps can be quite aggressive under the right circumstances. I've seen them raiding wild bees' nests on more than one occasion. Hornets tend to be quite mild unless you interfere with them; I've got really close to them (individuals and nests) without annoying them (move slowly is the key). So as long as the hornets have nothing the wasps want, or the wasps don't mess with the hornets, I expect there's no reason for them not to coexist quite happily.
