Cross Domain Tracking

Does anyone know if it is possible to track sessions across domains with Piwik? Also, if you have multiple websites filtering into one ecommerce website, would it be possible to have a goal that would show conversions for only the site that started the session for a particular transaction?

by default piwik will track session cross domains, if you put the same JS code on all your sites, the cookie is issued from Piwik rather than having a 1st party cookie like Google Analytics, yahoo!, etc.

you can track set your conversions using the domain you wish to track, eg. http://example.org/goal.html

what do you mean exactly by “show conversions for only the site that started the session for a particular transaction”?

I would actually want to use this for many different accounts but I think I have found a solution using json. Thanks for your help.
