The core concept is really 2 monk / 1 ranger; additional ranger levels are nice where they can be worked in, as they effectively give additional feats at at least the same rate as fighter levels (i.e. the ranger bonus feats at levels 2 and 4 are ones you'd want to pick up to boost ranged combat anyway).
You can bolt this onto things like 17 cleric, 17 FVS, 14 or 15Pal, and probably even 17 or 14-15 Druid would work.
The pyrene build presented in this thread is really just a particular instance of the 2monk/1ranger concept, and in all honesty the credit for this component probably belongs to Haek who used it for the juggernaut build (from what I understand of that build from the juggernaut thread, it started off as 2monk/2pal but the real stroke of genius was changing the /2pal to /2ranger, as the small ranger splash is much more synergistic with archery).
