Ubuntu popcon data - more detailed?

[Till Mossakowski]

Dear Ubuntu developers,

within the community project communtu (see en.communtu.org),
we want to implement an Amazon-like functionality for Ubuntu:
"users who have installed package x also have installed
package y".
In order to do that, we would need more detailed data
than those displayed on popcon.ubuntu.com, namely we
would need a list like:
* user a uses packages x,y,z
* user b uses packages u,v,w
etc.
Of course, we are not interested in identities of users,
so a, b ,... are mere placeholders here. However, the Amazon-like
functionality essentially depends on the information
that certain lists of packages are used jointly by the one and
same user.
We are aware of the fact that even this anonymous
information may potentially be used to reveal sensitive data
about users, and we will not make the data publicly
available - the data will be only used on our server,
such that only the admins of our project will have
access. The public will only see information of the form
"users who have installed package x also have installed
package y".

The implemented functionality may also have potential future
use within the Ubuntu software center (if desired).

All the best,
Till
