From the
d20srd:
We're not set up to do nonlethal damage, and the armor bonus clause is going to kick in pretty fast. Not to mention you're talking new animations, one of the more expensive development money sinks, for what amounts to a specialty weapon very few are going to use.
The usual response to wanting to keep some distance is to grab the repeating crossbow proficiency feat, which works pretty well on rogues and
some other builds.
###Edit###
Okay, I will admit dual whip monkeys would probably look just plain
awesome, but I've also been here long enough to remember the fifth dual-weapon attack animation, so emphasis on the "probably".
