Determine which Omniture software you're actually asking about, and try the relevant forum.
As Todd pointed out, the appropriate forum for this discussion would be: http://forums.adobe.com/community/creativesuites/omniture_extensions
That said, Adobe provides integration between Omniture SiteCatalyst and Omniture Test&Target and the following CS5 products: Flash Professional, Flash Builder, Dreamweaver. The integration is available at no extra cost, via plugins that you can download from this page:
However, you need to have CS5 version of those products installed and an Omniture login.

Let me know if you have further questions.
Hope this helps,
