Has sftp client like macfusion mac app ?

This app can mount remote directory via ssh as local directory. And then you can import all files to any code editor you use.

I tried vim and emacs depend on putty, they didn't work well. I have tried this app with TextMate on Mac. It's so easy.

I think that the core is same with winscp, just develop another GUI.
