It's generally the case that multi-classing happens for two reasons:
1/ You have a weak base class (Ftr), or want to add a bit of a good "mix-in" base class (Rog, Rgr, Ftr). In these cases, multi-classing is making you stronger, and thus might need to be limited -- or at least "qualified for".
2/ You need to multi-class to qualify for a PrC (El.Knight, Dr.Disciple, Ar.Archer, My.Theurge, Ar.Tricky). In this case, the multi-classing is making your character weaker (until you get half-way through the PrC). There should be no penalty in these cases.
So, that's what I was going for when I made my list. It's easy for Wizard to enter Cleric, becuase that's a weak combo. It's hard for Ftr to enter Barb, because that's a strong combo.
I'd suggest that you stay away from "throw away" feats for qualification -- that would make me unhappy as a player, having to waste one of my precious Feats. Skill ranks are less of an issue in that I get to keep them, and if I was going to spend them anyway, it's a bit of a hit (cross-class) up front but then I get paid back later.
