From your MDapps it looks like you've got a bunch of interviews and are having trouble scheduling them because of school/work/whatever. I'm kind of in the same boat, and here's what I'm doing:
-2 last week
-4 in the next 3 weeks (2 close, 2 plane rides)
-a few more that I will probably schedule for January (yes, rolling schools)
Basically my strategy is to hope for an early acceptance and then start getting selective. If it backfires it means that I'll be interviewing fairly late though, but if it's January and I don't have an acceptance I will have quite a few WLs, which will hopefully get me in somewhere.
Bottom line: Yeah, pushing them back isn't the most ideal situation, but you gotta do what you gotta do. Plenty of people get into schools that they interview for in December/January, and it looks like you've got a ton of interviews at great schools. I think you're in good shape.
