Thank you for all of the background on WebDAV, supporting it certainly
looks intriguing. Making WebDAV the only way to access construction space
will probably not work, though. Experience shows that expecting faculty to
have any functioning piece of software on their computer besides a web
browser ends up being a headache - CAPA has a lot of experience with
X-clients even from the time when we had only "power-users" ... I think we
always need to support the simple web browser interface.
