InfoPath Dev

Hi All, I want to create a workflow which internally has various stages of InfoPath form data collection

PartnerA fills out certain part of the form sends to PartnerB
PartnerB then fills out certain part in the form and sends to PartnerC
PartnerC then finally submits the Form to a repository

Any thoughts of accomplishing it would be appreciated!

BTW Once the form has left Partners A Desk he can't edit it 

Sounds very cool.  Looking forward to a response since it looks as though the "Partners" will have to entered within the form and that data passed to the workflow?  Somebody hurry up and answer this person :)
