I sent an email to Apani about getting the old beta Zaurus client and received the following response:
"We did have a beta Contivity VPN Client for Zaurus about a year ago. We have since decided not to add support for Zaurus at this time. I will note your request for Zaurus support to our Feature Request database, and we will contact you if that platform is added at a later date."
So, in case anyone was pining for the Zaurus client it definately looks dead. Persons that are interested in getting this client on the Zaurus could send an email to email@example.com requesting that they support the Zaurus.
