We haven't had any problems with scalability for the use cases we've got. There are around twenty users of this solution in my company. We don't have plans to increase usage. Now that everybody is working from home, everyone has their own laptop so coming through remotely is easy. All we have to do it set up the remote environment which is why we set up terminal servers. Everyone seems to work pretty well. We also use a terminal server which is less easy to manage.
