ideas for the api

bitcrunch.js

// http://amix.dk/blog/post/19714#bitmapist-Powerful-realtime-analytics-with-Redis-2-6s-bitmaps-and

var bitcrunch = require('bitcrunch')
  , client = bitcrunch.connect();

// mark user 123 as active and has played a song:

client.mark('active', 123, fn);
client.mark('song:played', 123, fn);

// timebased queries

var active = client.monthly('active', new Date);
var played = client.monthly('song:played', new Date);

// count the active users/players

active.count(fn);
played.count(fn);

// bit operations w/ composition

active
  .and(played)
  .count(fn);

active
  .or(played)
  .count(fn);

Finally got around to this if your interested in tinkering... do you happen to know of a decent, minimal command-queue / promise-like module for handling sequential chaining?
