"A WPA/802.1x client for Pocket PC 2002/2003 and Palm is available from Meetinghouse"
It does not mention the name of this software. When it really is Cisco Secure Services Client, like you suggested, then apparently it dropped PPC 2003 support, because I see only Windows 2000 and XP versions in the download section. Can you confirm this for me please?
I also saw in te section Mobile Wireless > Cisco Mobile Client, but that empty. Could it be that Cisco dropped it all together when it took over Meetinghouse?
OK, thank you, now I finally know the product name: "Aegis Client". I used it in a search term in Google and found some interesting pages. I encourage others to do the same and with a right combination of other terms you will find your solution in one of the many university sites.
