I replaced OnlyOffice with Collabora in my lab. I was able to extend their WOPI example to produce a Minimum Viable Product . As it stands now, the software is feature complete for my use case.

I replaced OnlyOffice with Collabora in my lab. I was able to extend their WOPI example to produce a Minimum Viable Product</a>. As it stands now, the software is feature complete for my use case. From there, I mount my data to my NFS storage and sync that folder with Dropbox. This lets me use a filebrowser for my currently in work documents. I can then access those contents from my reMarkable</a> using the Dropbox integration. Unfortunately, the reMarkable reads PDFs and not docx. To combat this problem, I have created a nightly script to convert the files to PDF. This is easily packaged into a container and run as a kubernetes cronjob. Since my NFS storage is also a persistent volume claim, I can reuse the same ReadWriteMany mount for both my Waffle WOPI server and the wrapper script to libreoffice.</p>
