When our local internet provider (Telus) first distributed wifi routers around 2004, they didn’t turn on encryption by default. I think I made use of nodes in the “neighbour net” for about three years before the majority began setting up WEP.

Akelpad is a nice replacement. I use it on my work laptop. It’s locked down so I can’t install anything, but I can use portable apps!

Late response. I used to host radicale, but switched to MyPhoneExplorer a few years ago. I just sync from the laptop to the phone over bluetooth. It does contacts and memos as well. Reminds me of the old Palm Desktop sync.
