Hello Siri,
Firstly, please notice that you've looked the supportability for the JAVA/WEB stack. For the ABAP scenarios, the NWSSO releases 1.0 and 2.0 supports CRM 7.0. You can see that in the attached document from the product in PAM.
Regarding not finding the product itself in the marketplace, please refer to SAP Note 1876552.
Best Regards,
Guilherme de Oliveira
