Your business ideas (that you're never going to act on)
Mine: what I do now but almost entirely remote working. You can do hearings by video conferencing now, but they're not that frequent, so use the facilities for client and internal meetings as needed the rest of the time.
Paperless, too. Would cut down on shitloads of admin, and support staff.
Use the massive savings in overheads due to requiring less admin time, support staff and office space to undercut your competitors and attract good staff who want the flexibility of remote working.
Or an all you can eat cake café.
