I installed Apani/Netlock Nortel Contivity VPN client on my Macbook, with the Tiger update. The software uses a browser as a GUI to the VPN client. When I enter the localhost port number the client uses to interface with the browser, the browser just responds with "cant find server". Currently the client is compiled for PPC only. I have read that folks were able to use the Windows version of the client within the Parallel VM. I'm currently holding off on getting Parallel, so hopefully someone else got OS X PPC client running under Rosetta.
