Is there a common idiom or method for distinguishing Iverson brackets from "normal" brackets?
In all examples I've seen, simple braces [...] are used for both; but in complex expressions, this can become confusing, as the only way to resolve which is which is by looking closely for the presence of an =.
Is there a good way to distinguish these typographically?

(Aside: Pairs of square brackets are used in many notational conventions, not just for Iverson brackets.) One of the principal obligations of any author is to avoid creating (unnecessary) confusion. If an author believes it's essential to use the Iverson-bracket notation to denote indicator functions, he/she should make every effort not to use square brackets in ways that denote other forms of usage -- at least not in one and the same expression. E.g., one could use pairs of round parentheses and/or curly braces instead of square brackets.

I guess I expressed my typography-related view too implicitly in my earlier comment. A bit more explicitly, then: Unless one is willing and able to add salient visual markers (tildes, above or below the brackets?; horns?; little bells?) to one set of square brackets and not to other(s), the chances that your readers will be confused to no end if you assign different meanings to various pairs of square brackets are just too great to tolerate. Either switch to other symbols (e.g., round parentheses, curly braces) for the "fences", or use another notational convention for the indicator function.

@Mico: Ah, I see: some unnecessary confusion. So the answer to the question asked is: "no"?

In the section entitled "Iverson's convention" in the article Two notes on notation, Knuth is noticeably (but certainly not surprisingly) careful not to use square brackets for more than one purpose in equations. (Square brackets are also used in the article to offset numerical citation call-outs, but that's outside the equation context that's relevant for Iverson bracket notation.)

You can use double brackets for Iverson brackets. In latex mathmode, you can use: llbracket from the stmaryrd package. In latex textmode, you can use: textlbrackdbl from the textcomp package.
