For those who care, the 31-char truncation can be increased via a compile-time define. No need for the ACS, thus far at least there are no identifiers in the system that actually clash in the first 31 characters, and if we find some I'd recommend we make them unique when truncated so folks don't HAVE to increase this limit.
But, I thought I'd point out that increasing it is possible, since Mike asked specifically.
