Can the SAP NetWeaver Business Client (NWBC) be launched from SAP Portal ?

After searching SDN, google and reading the NWBC30 documentation I have seen this question asked about a year ago and there was no solution. I would like to launch the NWBC 3.0 from SAP Portal 7.0. Our goal is to have all users access all systems from the SAP portal and use it as the SSO solution. We also want to have a consistent look and feel for all users be it portal or ABAP.

Has anyone gotten this working or is it even possible?

We will be upgrading our portal to 7.3 soon and I know NWBC 3.5 is not to far away from being launched so I have not read if this is a future plan?

Thank you.
