[Ipopt] MUMPS vs PARDISO

Yes.

Not sure what you mean by "this", maybe here:
http://www.coin-or.org/Ipopt/documentation/node14.html

Depends probably on the binary that you use.
If it includes the linear solver loader, then Ipopt may be able to load 
the pardiso library dynamically at runtime:
http://www.coin-or.org/Ipopt/documentation/node21.html
For the libraries in the *-dll.* archives, I do not know whether this 
feature is included, for the others it should be.
