Access sftp servers in the Finder

ExpanDrive is a very useful little utility which mounts sftp servers as drives in the Finder. There's been a few interesting things written about ExpanDrive including using it in conjunction with BlueHarvest to remove those sneaky DS_Store files. The only issue I've had is that on my MacBook Pro I had to connect to the server via the Terminal initially so I could approve a key file. I'd also like to see the ability to change permissions on the server in the Finder, but it's early days yet and there is a forum in order to express ideas and issues.

Note theres a free alternative out there called MacFusion.
