I was looking at my zimbra log file trying to determine why my zdesktop on 64-bit vista was hanging on the "loading" screen (turns out it was a huge sync), when I see my username and password to my zimbra account just sitting there between two <debug> tags in the log file. This is ridiculous. Sure its a beta, but lets refrain from writing cleartext passwords to a log file.
I have since moved to 64-bit Ubuntu, but there is no native 64-bit linux zdesktop. Since most power users are migrating to 64 bit linux, it would be great to have zdesktop on that platform without hacking to run a 32-bit version.
