Yes, it would be in TAO land.  However, this type of problem
is an extension of box-constrained variational inequalities
(which are being added to PETSc) to cone-constrained 
variational inequalities.  I've not delved into the 
algorithm employed, but there are certainly methods 
you could apply for cone constraints.  I'm just not 
sure how far PETSc wants to get into more general 
variational inequalities.

Cheers, Todd.
