I am 28 and except for a couple of interview questions that came from I am going to guess just individuals points of views (because traditionally they are schools that take alot of non-trads (GW))...if I were you I would still investigate every school...the schools that I thought were non-trad friendly-SLU, Penn state, temple I didn't get interviews at; the schools that I was told basically didn't matter who you were...cornell, columbia, bu, of rochester I got interviews....
I think the biggest question you should be asking is not which schools are non-trad friendly (which btw I think they all claim they are) You need to talk to individuals who go there, and find out 1) if the school is flexible when family/outside concerns come up and protentially even more important 2) talk to the older students and find out who the interactions with the others are, even though I know when I went on tours they said they love older students, yada yada yada...when I emailed a student (4th year) he said that he had alot of trouble working with his classmates, they were not very accepting of him and his views....[again this could be just an individual's point of view]
I have to admit I think non-trad is almost going to become traditional soon
