People around here seem to like FreeNX quite a bit, no real experience
with XRDP so can't compare the two.  But FreeNX is faster than either
VNC or old school X forwarding.  Of course OpenStack can only handle
the redirected console through VNC, but presuming the instances are
running properly with the right public IP and security group setup to
allow it this won't get in the way of NX as a service on the VMs.
