I thought I posted an interesting selection of examples
I'm recalling where Fafhrd batted away a tankard thrown at him (full or empty, I know not) in a Lankhmar story and I think that's reasonable to be able to do. And say it was a full tankard, and the character wanted to catch it and chug it - a superstylish move, what to do about that?
As for blocking the thrown dagger with a buckler, I'll look at the mechanics when the book comes in next week, but I'd allow it, not as DR, but actually allow a parry result, if attempted (e.g., someone might be sitting, and not able to dodge but so well).
And what about simply catching the thrown dagger, ala Big Trouble in Little China, any option for that? Perhaps a Feat idea?
