In the course of doing some work recently I came across genealogical numbering system that I'd never examined in any detail until now. It's called "Ancestral Lines Pairing System" or Ancestral Lines for short. (Link below)
It is a compact numbering system, so it generally takes less space than Ahnentafel numbering, and in one of its three variations it can handle both siblings and multiple pairings. The price, however, is that the numbering schemes are more esoteric and generally less intuitive than Ahnentafel binary Ahnentafel, etc.
What are your thoughts? Would you use this numbering system on reports in FTM if it were available? I'm wondering if it's worth the enhancement request.http://www.americanancestors.org/ancestral-lines/
