Do Americans find a date such as 11 Apr 2012 more readable than the ISO format 2012-04-11? The reason I ask is that there are many situations where we do not have access to the locale, and even if we do there are often no locale-sensitive formatting functions that we can use.

American date format is
mm/dd/yyyy but you are talking about
dd/MMM/yyyy which doesn't match with American date format.
The U.S. military uses the 11 Apr 2012 format (
DD MMM YYYY, or
DD MMM YY), so as to avoid ambiguities between 4 Nov and 11 Apr (4/11 and 11/4, not necessarily respectively, depending on where you reside).
The format is more uncommon outside of military correspondence, but I don't think anyone would tell you that such a date is "less readable" – maybe "less familiar."
I think the ISO format (2012-04-11) will be slightly more jarring than 11 Apr 2012. However, if you're using numeric months, that might be a good thing. I suspect most Americans will associate 11-4-2012 with the 4th of November. The ISO format might make us pause, but it won't be confusing.
