Dreamhost API
From this page you can download a .NET library allowing you to use the Dreamhost API from a .NET application.
Details of the API can be found on the Dreamhost Wiki.
Documentation on the use of this library will be available soon.
Mono Notes
This library is compatible with Mono, but there will probably be connection issues as Mono does not trust anybody by default. More information can be found here.
You can follow the development of this library through the SVN repository at http://svn.clempaul.me.uk/dreamhost_api/ or using WebSVN at http://svn.clempaul.me.uk/listing.php?repname=DreamhostAPI
