Java only used for mouting images. KVM is transfered via VNC protocol

They're not re-inventing the wheel, but I think KVM is generally some
VNC stream embedded in http(s) which VNC clients can't seem to
understand (at least, at a glance, I haven't been able to connect to
iLo, DRAC, Spider, or Tyan IPMI from outside the Java app).
No, at least on SuperMicro it's a hacked up VNC protocol.  It's not
embedded in HTTP/HTTPS, it just uses HTTP/HTTPS to fetch the Java app.

I say hacked up because it's got a custom auth method, and a whole bunch
of undocumented extensions.  I looked into implementing support in noVNC
for it, but reverse engineering a binary protocol is a bit beyond me.

While there is no spec, there are people who have reversed it:
