I addressed jointing extra long boards in a post a few years ago. (my how time flys) I found it in a search, but unfortunately the pictures are no longer there.
The key to my success in jointing and gluing boards, up to 8 ft long, is a Veritas 50 inch straightedge. Also needed is a "rock solid" roller stand like Rockler's Heavy-Duty flip top stand. Using feeler gauges I level the Rockler roller stand about three to four feet out from the 4" jointer's outfeed table. This is actually pretty easy to do in short order.
I also use a lighter duty roller stand about the same distance away from the infeed side. The infeed is not as critical as the outfeed, but I use the 50 inch straightedge and feeler gauge there also.
For gluing long boards, a tip that I picked up from a Taunton DVD, is to take a hand plane (I use a #5) set for extremely thin shavings, clamp your jointed board on the workbench, and make a few strokes, starting in the middle, and then lengthing the cuts toward the ends. This creates a small amount of "spring" in the middle, and helps to keep the ends from separating over time.
At the one and only Shopsmith week-end back in '08, I saw a jointer outfeed extension made by Nick Engler that attached to the auxiliary fence. I made some sketches and measurements. Then realizing that I might be "stealing" Nick's idea, I asked him about it. He said that I could make one for my own use, but that Shopsmith was considering making this product. I didn't feel comfortable with that so I destroyed the sketch.
I believe nick did include that in a saw dust session. His did rely on the shoulder that an older jointer does not have.
I think a shoulder could be bolted on to the jointer. Surface roughness could make that a bit difficult.

Yes, I did see the sawdust session where Nick showed the jointer outfeed extension that attached to the auxiliary fence.
