In regards to question #1, Amesos can be used by NOX via the stratimikos
interface to linear solvers. NOX uses the stratimikos interface in both
the src-thyra and src-epetra (NOX_Epetra_LinearSystem_Stratimikos.H)
layers. You could use either to get access to Amesos/MUMPS in NOX.
There are no concrete examples using Amesos in NOX, but it should work.
