I'm an outsider to this project and don't want to ruffle any  
feathers, but if PETSc is going to be the intended back end linear  
algebra library, then consider this.  Instead of trying to maintain  
your own solver database within dolfin, wouldn't it be easier to rely  
on the existing, well maintained, PETSc database and provide a path  
for sending the options through a lightweight interface?
