I tried to think of ways to show rolls nicely inline with IC posts, but didn't come up with much.

The only way I can think of, besides an obtrusive block code, is to use the acronym/abbr html tag to display the dice roll on hover. So you could make a custom BBCode that takes the roll ID, displays the roll results in the hover, and then let someone write their action (as a result of the roll) inside the tag. Similar to the implementation of URL=, but hover instead of link.
