I don't do much remote work but I am always trying to promote teamwork across sites. I use Trello for grouping projects with some success. Slack a bit for chat. Currently trialing shelf.io as a repository. It syncs your dropbox and drive etc and adds wonderful search capabilities, even inside scanned pdfs. Everyone can dump all the project docs in and you can still find what you need quickly.
