Xpra can also stream rootless single windows, to html5 or other Xpra clients. I found it annoying with a bunch of sharp edges compared to getting a full desktop, though. You must have a different use-case :)

I used to use WinSwitch instead of just plain Xpra, which was nicer. I think it may be unmaintained now.
