The current development plan mentions adding a Nucleation object with a
spatial and temporal perturbation of tractions from the initial value. 
This type of variation is required for the SCEC dynamic rupture 
benchmarks that use rate- and state-friction. This is listed as a likely 
feature for version 1.8 that has a target release date of Fall or Winter 
2012.

You can create a spatial database of initial tractions from the final 
fault tractions of a quasi-static simulation. This involves creating the 
header and writing out the values from the output file. This is most 
easily done with HDF5 output.
