i just uploaded the z3c.widget 1.0.6 egg and am trying the use-cases  
below.

o.k. fine, you're actually right.
i'm wondering why i couldn't fine  zope.app.wsgi = 3.4.0b1dev_r75415  
after 3.4.0 was released a few days ago.
probably someone in [philikon, ctheune, J1m, baijum] removed the egg?
we nailed the version to 3.4.0b1dev_r75415 (and i have still this egg  
in my cache), but it disappeared from the rest of the world.
this should never happen for released eggs, they should be considered  
read-only imho.
sorry for blaming pypi/setuptools for this :)

i'm not talking about the index, i mean the actual download. http:// 
download.zope.org/ppix/z3c.widget/ still points to pypi.python.org
is there a way to change this? mirror it?

agree
