yes, creating a portable install makes sure that everything (all settings) are stored under a single main folder. If the settings have to be shared on multiple platforms, it will probably get more dificult to keep all installs sync'ed, though. You can also use the import/export function in the Reaper preferences to exchange settings (even across platforms). I created a portable Reaper install with everything I require. The only things left at default were the audio and MIDI device settings. I then gave the zipped install folder to others. As I rather frequently update my own preferences (keyboard shortcuts, tool bars, actions, scripts) I have to import and update those settings from time to time in the collaborating installs. I think it's worth discussing and normalize the way to create and manage projects and to find some common guidelines to make project exchange as smooth as possible. First thing is to have a common project storage path scheme/structure if possible. Having a main Reaper project folder is the starting point. I then have sub-directories for each client/artist (labelled by client's/artist's name). Below this folder, I create project folders for each project/song (labelled with the project's/song's name) in which the actual project files are stored. Basic project template settings are also shared. Among the settings is the common project sample rate, recorded file format, video frame rate, pan law and a relative media file sub-folder. You can further enhance the user experience by tweaking Reaper's naming scheme for recorded files and master file labelling in the render dialog by using the power of Reaper's auto-labelling wild cards. I find that exchanging track templates (including media items and automation data) instead of project files is often prone to less hassle when sharing projects because this doesn't mess with local audio input and output particularities for instance. All Reaper installs should use the same master output routing. Another topic is plugin management. Every member of the group has to have the same plugins to make project data play identically. It might be a huge challenge to consolidate this. Using WavPack of FLAC as the default recorded files format allows for much smaller project media file sizes and faster transfer via the internet without compromizing audio quality. Those file formats also support to include meta data (notably positioning data which allows them to automatically find their original position in a project). .
