Suggestion : M-turk like feature but in a Local server

Hey guys, thanks for the awesome annotation tool.
1) Is there a way to use Label-Me similar to M-turk mode but used within the organisation via LAN?. I mean asking the human workers in the organisation to label the images using Label-Me which is running on a local server?
2) One idea to make the above possible is to host label me on a local server and ask the workers to sign in with different usernames and label
3) The main problem is in determining the accuracy of the labelling by different workers . Is it possible to do something like [this ](https://blog.mturk.com/tutorial-measuring-the-accuracy-of-bounding-box-image-annotations-from-mturk-ad3dfcdf8aa0) using label me?

or any other suggestions on determining the accuracy of labelling?
Thanks in advance.
