Actually, that wasn't a bad idea. Using the hypothetical data set from my response to Eric below, I benchmarked the 2 subs initially posted in this thread. At 50k iterations, here's what I got:

Benchmark: timing 50000 iterations of mybinary, use_grep...
  mybinary: 15 wallclock secs (15.23 usr +  0.03 sys = 15.26 CPU) @ 32
+76.54/s (n=50000)
  use_grep: 13 wallclock secs (12.83 usr +  0.04 sys = 12.87 CPU) @ 38
+85.00/s (n=50000)
           Rate mybinary use_grep
mybinary 3277/s       --     -16%
useagrep 3885/s      19%       --

I have not yet tried BrowserUK's latest edition sub yet. That's for this afternoon/evening.
