so to sum this up:
1. there is the new dialog to open vnc manually.
http://gerrit.ovirt.org/#/c/4790/
good
2. Alon suggested it should be allowed to open this dialog for spice
as well, not only for vnc.

3. Alon also suggested to have a launch button on that window (or
parallel to it) which will try to launch vnc or spice by returning a
specific mime type response, allowing client to choose the vnc/spice
client to run for this mime type, and passing command line
parameters to it in the mime type reply.

I like the idea of being able to launch vnc and spice from the same place.
4. provide a vnc xpi/activex wrappers to allow launching it via web
browsers like spice
main limitation of this compared to novnc is you need to do this for
every browser/platform.
I like the noVNC option better since most modern web browsers support
the canvas element of HTML 5. With noVNC we don't have to port to
other platforms/browsers.
5. novnc
5.1 novnc client - i'd start with the one recently pushed to fedora.

that is an added advantage.
5.2 novnc websocket server - i see three options
5.2.1 extend qemu to do this, so novnc can connect to it directly
like we do today for vnc/spice
5.2.2 use the python based one from:
https://bugzilla.redhat.com/show_bug.cgi?id=822187
5.2.3 look at a java based websocket solution, assuming easier to
deploy it as part of webadmin/user portal war than another service
(requires a bit of research)
looking forward user portal and webadmin would be deployed on
multiple hosts, so a websockets would need to be deployed next to
them.
I can see myself going either way with java or python based websockets.

from the little i looked at, the various websocket implementations
are mostly nascent and are not scaleable/robust/etc.
I'd love to be proven wrong, and worth playing with them a bit to
measure that.
6. spice.html5
while very nascent - worth mentioning on this thread and trying to
take a look:
