I propose a gobby service be provided, perhaps gobby.fedoraproject.org.
From the package description:
Gobby is a free collaborative editor. This means that it provides you with the possibility to edit files simultaneously with other users over a network. It supports multiple documents in one session and a multi-user chat. I see several uses for this, primarily in package spec review but also in document editing or collaborative hacking.
