[support] Email Marketing with Interspire and linkage with Drupal User Base

Hello All, I have come across E-Mail Marketing Framework module that provides support services with few email programs like Mailchimp and Interspire. However, the versions are up to D6. I am not sure if anyone has done development work on integrating Interspire and providing support with D7 version of E-Mail Marketing Framework. Can someone kindly point out any work in progress in this regards or provide me assistance in development? Many thanks and regards, Quaid J. Surti
