Most Projectors of any quality have edge blending built in... all you really need is the Overlap... What is the resolution of the Playback? does it have to be live or is it jut a loop? There are a few Alternatives to watchout, just need to know more about your application..if your projectors don't have edge blending then there are some Flight simulator apps that have the blending.
Your Right .8 lenses will be hard to blend as they "round out the image" .... its hard to make it Seamless with a .8
with a muti server set up you maybe use a resolume system..
