BusyBlog bashes CalDAV...or somebody

The controversy about supposed shortcomings of CalDAV takes another twisty turn with this post from BusyBlog. Cmon Swampers...someone explain this to me. Is this read-only iPhone problem the fault of CalDAV, or Google, or Apple? Seems like using a solution like BusySync gets around the problem altogether. Does this suggest the need for a standard beyond CalDAV? Maybe it exists already, and I'm not paying enough attention?

Google Calendar adds CalDAV support

Google updated Google Calendar, adding CalDAV support. +1 SwampDrain point for Google.

I'm looking forward to the day when everyone who should supports CalDAV.

UPDATE: The Spanning Sync blog claims that calendars synced with CalDAV become read-only on the iPhone. Yikes!! I hope the problem is just the way Google Calendar implements CalDAV...and not a problem with CalDAV itself.

TimeDriver, HourTown: Any experiences out there?

Found on the Web: TimeTrade, which bills itself as "the world leader in customer self-service appointment scheduling" offers TimeDriver, which has been in public beta since August. It supports the usual calendar formats -- Outlook and Google Calendar -- but I haven't heard any unusual buzz about it. I think it competes with HourTown.

Has anyone reading this blog been on the receiving end of any appointments scheduled by either of these services?
