I experimented with this early on at Orange for Elephants Dream, and 
seemed that 'junkster.blend' where the idea was to populate a hand-made 
floor mesh with random items from a library has been archived at 
http://wiki.blender.org/index.php/Extensions:Py/Scripts/Manual/Add/Junkster

Here are the relevant sources from junkster.blend LibAppend.py and 
CreateTest.py

import Blender
from Blender import Library, Scene

scene = Scene.GetCurrent()

elephantdir = '/home/antont/elephant'
junklib = elephantdir + '/production/lib/machine/pieces/randomjunk.blend'
print Library.Open(junklib)
#Blender.Lib_Open(junklib)

groups = Library.LinkableGroups()
#for db in groups:
#    print "DATABLOCK %s", db
#    for obname in Library.Datablocks(db):
#        print obname

scene.layers = [20]
if 'Object' in groups:
    appends = [Library.Load(obname, 'Object', 0) for obname in 
Library.Datablocks('Object')]       
    Library.Update()
   
else:
    print "no junk objects?"
print len(appends), "added"
scene.layers = [1]
Library.Close()

---

junknames = ['suikero', 'purikka', 'tikkaat']
junks = [Object.Get(name) for name in junknames]

for v in mesh.verts:
    new = Object.New('Mesh', 'gen')
    new.loc = variate(v.co, 0.2)
    source = random.choice(junks)
    new.link(source.data)
    scene.link(new)
    new.size = tuple(variate(new.size))
    #new.setSize(variate(new.size))
