" A great pity that it has gone proprietary for the latest version. "
NX started as proprietary... yet http://www.linuxjournal.com/article/8477?page=0,1
"In these various messages, Gian hinted at the commercial NoMachine NX Server product. The features he outlined sounded exciting enough, but it was another message I took from his postings that thrilled me the most. It was how he outlined that NoMachine had released its main intellectual property, the core NoMachine NX libraries, under the *GPL license*. He wrote, "It is there and everybody can use it."
So the mechanism (protocol addition) is free... still is... but blindness has a price... why maintain a free version when there is no "support"... i would do the same, improvements only on the proprietary "version"...
And the funny thing is that NX seems to address many of the issues that were discuss about wayland... most could be used not only on the context of remote display, but local also...
* an efficient compression of what normally would be X traffic
* an intelligent mechanism to store and re-use (cache) data that is transfered between server and client
* a drastic reduction in multiple, time-consuming X roundtrips, bringing their total number *close to zero*.
(there goes the walala hype down the drain)
So it seems clear to me its not a copy or derivative of Xnest.. at all..
And i couldn't think of a better addition to the all X protocol than this... but sometimes wonder if Xorg has any say, or only does what its told to do, and that is why it has been "striped" and now positioned to be "finished"... hope the distros could take a serious look at this situation and take over, hire a "Ninja" or two, fresh ideas, specially the desktop oriented ones... their future is in jeopardy.
