Just to be clear, it isn't my site, it belongs to Tomorrow and Martin. Haha, it may sometimes seem like my site, because I post a lot.
Well, all puddings are supposed to be refridgerated. However, the recipes for the cooked puddings that you saw, I must admit, for home use, I have left the cake filled on the counter for a day or two with no problems. I hesitate to say that, because generally things like that should be refridgerated and if I was using it in a cake for the public, I would refridgerate it. I had a similar discussion with another Cake Central poster who found a similar recipe that stated you didn't have to refridgerate. However, not knowing the timeframe of when the recipe was first posted, might make a difference. We are much more cautious in our use of dairy products and though some folks are fine, the elderly, small children and some diabetics are more susceptible to food poisoning issues as are those with compromised immune systems.
Not sure what you mean by a link for recipes, I actually posted filling recipes on the site. Tomorrow also has recipes posted on her own personal part of that site.
Hhmn marshmallow dough is just another term for marshmallow fondant, I do believe. I am trying to remember the post, I think one of the folks just used that term instead of fondant.
Hope that helps,

Even the little pudding cups you buy, must be refridigerated once opened and any cakes filled with them, likewise must be refridgerated according to the manufacturers.
Likely you can buy some sort of commercial sleeve type filling in the U.S. that doesn't require refridgeration, but I haven't got access to these products so I am not certain.
