Would it be possible to install a shapespark project on a cloud drive (https://owncloud.org)?
From a brief search it seems like owncloud doesn’t support website hosting (https://central.owncloud.org/t/can-i-host-a-website-at-owncloud/1579/2 and https://forum.owncloud.org/viewtopic.php?t=30774)
If it acts like a local file folder (similar to Dropbox), you could use it to share the scenes folder, but this would require clients to have Shapespark installed.
Okay, Thank you for this idea. Probably this is not an option for the client.
