DropDAV is a nifty service that enables you to use Dropbox with WebDAV clients. It was developed to work with the (s aapl) iWork suite for the iPad, but it will work with any WebDAV client, so you could also use it to sync OmniFocus through your Dropbox account, for example.
It’s simple to set up, although you do need to provide it with your Dropbox username and password to get going. Once set up, you connect to https://dav.dropdav.com with your WebDAV client and log in using your Dropbox credentials.
DropDAV costs 30 percent of your Dropbox plan price, so it’s free for users with the free 2GB Dropbox plan, while users with a 50 GB account will be charged $3 per month. A 14-day free trial is available.
I’m surprised that Dropbox hasn’t added WebDAV support to the service it provides; it’s something that many thousands of its users have asked for. But until Dropbox adds built-in WebDAV support, DropDAV is a good workaround.
