Is there a way to edit views fields in place?
Try editablefields-d7; as reported by the project page the module is a Drupal 7 port of editable fields.
The project is a sandbox project, which means it doesn't support releases, yet, and drupal.org doesn't automatically create the archive containing the module code; this means the code should be considered experimental, and you get the code using git, using git clone http://git.drupal.org/sandbox/damz/1130436.git editablefields_d7 or the link to the snapshot archive.
