When I ride my upright bike and I see bumps/rough pavement ahead I naturally get the weight of my butt off the seat and use me legs as a "suspension". What do the recumbent folk do? One can't raise the butt off the seat, right? Just suffer through the rough stuff? Is it too bad to worry about?
Most of the time I just let the mesh seat take it, and my Giro's monotube seems to soak up a bit too.
When it's very bumpy I push against the seatback and pedals and raise my backside off the seat. It does mean I can't pedal at that moment but most of the time that's not a problem.

Are there any successful suspension designs out there?

Yes, i would say so. There are several. I have a cruzbike Freerider, it has nice suspension. But the other bikes i was considering, HP Velotechnik Spirit and a similar from Optima has suspension.
Some trikes even have suspension, and i've seen some guy drive like crazy on it. He even tipped it up at 2 wheels.

Recent trikes made by ICE have a rear suspension (www.trice.com). It works well enough to take the edge of rough pavement, but all the Tricen are tadpoles. My HP Velotechnik Speedmachine is a fully suspended lowracer and the suspension is superb and having two wheels there is none of the side to side pitching that happens with my Trice.
Stein trikes in Germany builds full suspension tadpoles. (link http://tinyurl.com/orh72). I don't have any experience with Stein, but there are some You-Tube videos of them in action.
AFAIK Sun has or had a delta in the product line that had a front boom pivot/spring/shock.
Bumps on a recumbent are not the painful experience that they are on an upright bike. ,,,, Also--recumbents tend to run tires a bit fatter than what typical road bikes will, because of the fact that you cannot lift off the bike to absorb bumps. The roadie-style recumbents are built to be lightweight and fast and come with road bike-width tires, but a lot of "all-purpose" recumbents come with smooth tires that are around 1.5" wide.

There are lots of suspension recumbents available, although the prices go skyward pretty quick. And I don't know of any suspended delta trikes right off. ~
my guess is that something is coming out in patents concerning the problem; producing them in trikes or whatsoever can take years; patents tend to be quite unpractical or /and costly; during ten years I introduced theory to solve problems with meeting bumps to quite a few persons and producers and in England the answer was something like : "your theory is worth nothing to us", in my own country I was told it was costly and I was also told to market the idea to producers making human powered vehicles and especially for handicapped persons ; now I think next ten years in developing the idea will make use of it...

I saw a link to a suspension wheel hub somewhere... I wonder how well it works. I like fast skinny wheels/tires from my upright racing years.

Pantour suspension hub. It doesn't give much travel so don't expect it to take out a pothole smoothly. What it's for (and reportedly very good for) is just easing out the small bumps on "normal" surfaces.
Only ever seen two sided ones, so that would just be the leading wheel on a delta. Something like a kettweisel there's little weight on the front in any case, so of limited use there, perhaps?

Look into getting a seat that uses stretched fabric, rather than a solid material. A friend who is a longtime designer of recumbents, swears by this type of seat for comfort.

I've never tried one but most people I have heard talk who have tried Pantour hubs say they aren't worth the bother. ---- Also I don't think it is any patent issue with suspended recumbents, it's just the high cost involved in a lot of parts to be made and welded together. ---- If you get a bike that can take fat tires, you can put wide rims and Big Apples on and run them at pretty low pressures (30-40 PSI). That's not quite the same as actual suspension but it can still be useful. ~
