This is really good. Mostly ready for integration. Just a few comments follow.

Besides these, it's fine to do that in a different CL, but it'd be superb to
have an integration test that worked against the real Amazon service. See the
other packages to get a taste for how it can be done

https://codereview.appspot.com/6586073/diff/1/iam/iam.go#newcode27
iam/iam.go:27: endpoint string
The endpoint should be integrated into goamz/aws.Region

You'll easily see the pattern there.

https://codereview.appspot.com/6586073/diff/1/iam/iam.go#newcode130
iam/iam.go:130: return fmt.Sprintf("%d - %s (%s)", e.StatusCode, e.Message,
e.Code)
This would be better as:

var prefix string
if e.Code != "" {
    prefix = e.Code + ": "
if prefix == "" && e.StatusCode > 0 {
    prefix = strconv.Itoa(e.StatusCode) + ": "
}
return prefix + e.Message
