Smarter way to check proximity over many objects?

    Hello all,

    Does anyone know or have heard about a clever, faster way to check for proximity between individual objects in large groups without a nested for loop?  I've always done:

    for object in parent.GetChildren() :
    for everyOtherObject in parent.GetChildren() :
    ##Find distance here (ouch!)
    if distance < thresholdValue:

    But it seems so dumb.  Do you guys have any suggested reading or know-how on the matter?  Seems like someone would have asked this before, but I either overlooked a post or I'm not using the right search keywords.

    Thanks a million in advance.
