No, if text looked horrible then this is something else, more than likely you ended up with a sub-par encoding (probably vp8). h264 will normally run in high quality mode unless you are really struggling for bandwidth, and with lossless auto-refresh you won't even notice the occasional lossy compression. With default settings, text looks just fine - I use it everyday.

There is a proof of concept which you can try: https://www.xpra.org/trac/ticket/473

Not sure what you mean by that, can you clarify? The rendering on the server is done using a regular Xorg server, it will use whatever settings you choose. If you use an xpra lossless mode (or lossless with auto-refresh), then this is exactly what you'll get on the client. Now, if you mean sub-pixel hinting, that's a different story.

That's just not true anymore. You can get a desktop mode by running Xephir inside xpra.
