Code refactoring on remote file

I am not able to refactor variable names on files opened on remote servers. Is this a feature or am I missing something?

Code Refactoring does not work in a remote file (because code intelligence doesn’t work over a remote directory), though I don’t see why Extract Method and Rename Variable shouldn’t work (as they just work on the file content and not over multiple files).

Update: Komodo 9 will allow Extract Method and Rename Variable on remote files.
