[omi] cargo trike - cargo up front or cargo behind?

cargo up front: http://blogs.sfweekly.com/thesnitch/CargoTrike.jpg http://www.examiner.com/images/blog/wysiwyg/image/amsterdam_cargo_trike_mom… pros - can see the load, no need for differential, use existing drivetrain w/o modification cons - looks a bit silly, unfamiliar handling, more load on articulated joint cargo behind: http://i01.i.aliimg.com/photo/v0/516041935/Electric_cargo_trike.jpg http://www.oushun.com/UploadFiles/2010319195936678.jpg pros - clear view ahead, load acts as crash cushion against road rage cars, feel like a trucker cons - complicated drivetrain involving a differential, cannot see if passengers are misbehaving Either way, it would be sweet to build a modular cargo/pedicab platform. Maybe a 4x8 version to start - that's one sheet of plywood. A buddy in austin wanted to build some pedicabs and mentioned that for left/right brakes it might be better to use hydraulics so you don't have cable lengths to deal with, just distributing pressure in brake lines. Thoughts?
