Hi Abraham, This sounds like a great project -- I've always wanted to read the Bryant/Griffiths books on EDS but I've always been too lazy to do the computations myself and get a proper grip on the subjects. Such a Sage package could be a great help.
I'm not entirely happy with the way that the current implementation of DifferentialForms relies so much on CoordinatePatch, and I'm sure there's room for improvement here.
