EDIT UPDATE (changed title):
Got this today (Wednesday, April 27, 2011):
I finally talked with White Industries. They are working on designing us a dual bearing freewheel. They just needed to confirm a few design issues with us. I don't have any time frame but they are working on it.
If you would like to purchase a high quality Flanged White Eno Freewheel (or multiple Freewheels) similar to the picture below, with a Dual Row of Bearings please let me know.
You can post to this thread or send me a PM.
This thread was inspired by mmd's suggestion and my emails with Jim at Sick Bike Parts:

I sent this to Jim at Sickbikes:

And I got this response:
sickbikeparts.com wrote:Yes we are aware of the problem as it applies to mostly electric applications as the angular loads are much greater with an electric set up than with our gas jackshaft set up. We have contacted White about making a dual row bearing freewheel for us making a much more bullet proof set up. They said they would work on it but we haven't bugged them about it lately. I will contact them again and see if we can get the project started again. I will let you know what they say.
My reply (hopefully not a mistake!):

sickbikeparts.com wrote:Yes some input about quantity would help.

Destroyed! A warning to those using freewheel cranks....
Another option might be a one-way:

If someone can design and equally robust and affordable solution, and its the preferred method, maybe we can organize a small run of parts or kits?
