Well it doesn't require a Braille display. The resulting tty can then be read by orca on the local machine using voice. You may have to set up things in a fashion that is a little more complex than I had hoped. If you don't use my complicated method you will end up having to switch between two displays(one display where you read the text, another(invisible) display to interact with. We don't want that)
Here is the set-up I have in mind which gets around that issue(keep in mind that brltty can also read things aloud, it need not send them to a Braille display).
Remote machine:
brltty with tty driver + orca
Local machine:
One tty displaying the remote brltty tty. This tty will be read aloud/displayed by brltty.
One X display displaying the remote orca enabled x session.
The key to this setup is understanding that brltty is capable of sourcing it's text in a number of different ways. When brltty is used with orca, orca sends text to brltty through brlapi. But brltty does not need to receive it's text from orca, it can get it's text directly from a tty. So in our set-up the local brltty instance is not reading the text from orca at all, but directly from the remote tty.
I hope this helps, and doesn't merely send you guys down an hours long rabbit hole :)
Perhaps in the future I could work with Joanie to get orca to attach to a remote Virtual(that's another driver for BRLTTY that operates over TCP/IP) display. Glancing at the README for that though it looks like it might be a bit tricky given that the Virtual driver currently doesn't handle security issues.
I know that the Braille displays are way to expensive :( Even Samuel(a sighted developer who has been working on brltty directly for many years doesn't have one. He tests out his work by way of an emulated visual display.)

Well, that might work for someone with a braille display, but the
problem is it assumes the person actually has a braille display. If
they don't have a braille display the solution you gave is pretty much
useless. Any other ideas how to do this? Hopefully one not involving
an extremely over priced piece of hardware?
