I've already stated my opinion on this matter, so I won't state it again.
I will not try to pre-judge a study I have not read (regarding the solid
support) but it seems to me that if you are analyzing the binding of a peptide
to a protein, that is fairly straightforward MD without anything fancy.

Build a surface, create a merged moleculetype, and define bonds between protein
atoms and surface atoms. This all sounds like a ridiculous amount of work.

IMHO, it's not worth doing in this way.
