DreamMount is a Mac OS X application that allows you to mount DreamHost domains or users to a networked filesystem, allowing you to access it using any application.
Release 0.1 contained a bug, resulting in time-out errors to many users. Version 0.2 fixes this, so download this new version from http://www.dreammount.com/.
Stay tuned, as I will be releasing another new version in the next few days. This 0.3 version will be updated to support additional features added to the DreamHost API during the last few days.
