I work at 75% mac shop and we have a lot of iPhone users, including myself. So I paid $6 for the one at remote-calendar.com which works great but it doesn't let you add a new calendar entry. I want to read/write from either the web (works fine of course), Thunderbird, or iphone.
I guess I could do something like: cron fetchmail to check for a properly formatted email from that account, parse out the calendar data and feed it to zmsoap. is there a better way?
