THis demonstrates a problem or two with Worldpilot. I would defintiely _not_ use
worldpilot in that setting. Why not? Well, the sharing capability (IIRC) gives a list 
people on the system you can share with. Think about that for a moment. Four hundred
thousand people. One list. It would  be nice if it were possible for people to not 
in the list, and for there to be groups.

THe way I would see that working is that by default, a user is not liste din the 
options, and has a checkbox to change it. Then, they could be seperated by groups, 
on some algorithm, or by other logical divisions (marketing, webusers, R&D).

Well, what you are describing really isn't a test of Zope's scaleability.
, but rather workdpilots (and the machines's).  

Zope's scalability in this case is more a matter of resource usage, than a funtion of 
number of users. Thats is to say, what is the expected load of the machine/site. 
users will not access all at once, will they? Zope can be scaled accross multiple
machines, through the use of ZEO, so if your load gets too high, you can move to a ZEO
solution, adding machines as neccessary.

One caveat to that is that worldpilot stores data on the filesystem, so that data would
need replicated accross the sites. Perhaps NFS or Coda could server this function.

Well, I'll stop rambling now. ;)

Do not meddle in the affairs of sysadmins, for they are easy to annoy,
and have the root password.
