File browser for iPad Is there an app for the iPad that let's you view an NFS share?

It seems like File Browser lets you mount SMB shares and iFiles lets you view different cloud storage sites like Flickr and other file shares such as FTP but neither support NFS or SFTP? Is that correct?

Thanks for your input!
Air Sharing HD supports browsing SFTP (among many other protocols, but not NFS) and works well. It's the best iOS file browser I used up to now.
