I've done this in small applications in C (where nodes were already being statically allocated) and/or assembly (hacking on an existing binary).

No idea about the effect on speed in general; I was trying to save a few bytes of storage in a place where that mattered.

I had a decent sized C library that I could conditionally compile (via macros and ifdefs) to use pointers (64-bit) or indexes (32-bit), and I saw no performance improvement, at least for static allocation.
