OpenGPG for collaborative file sharing?

We are trying to create a system where our employees can access are shared encrypted file over a VPN and make edits to it. The file's contents are sensitive, so we want to make it as secure as possible with a small budget. However, we definitely need to access the file off site.
We are looking for the most secure ways to encrypt the single file. I like OpenGPG because you can use both RSA and password-based encryption simultaneously. However, I'm not sure it works very well for this use case because employees will be making continuous edits to one file. When you decrypt a file and edit it, it produces a cleartext file that must be re-encrypted, and when you re-encrypt that file it keeps a copy of the cleartext file which must then be deleted. I'm fairly we don't want to be working with/deleting cleartext versions of the file.
We've looked at EFS (which isn't an option due to the restraints of the file location), Axcrypt (which is an option, but comes with OpenCandy), and LibreOffice/Excel encryption (which is looking like the best option right now).
Is there a way to use OpenGPG in this use case, or are we better off with something else?

File encryption protects data at rest... so, if people are editing a file, there is a clear text version somewhere, if only in system memory.... If you are looking at numerous people collaboratively working on a sensitive file, the encryption options are going to be limited and cumbersome. Since the VPN already provides for eavesdropping protection, it may be better to implement an ACL approach with the file being encrypted via a master key when not in use. Something like this
