I recently implemented Morphic (well not exactly, but something very very similar) in Java. I had to use a lot of dirty tricks to get the required performance, although I must admit that with Hotspot (how ironic, that so many ideas came from Self, and yet Self was displaced by Java) on NT it really flies. I would have grave misgivings about implementing Self on Java. BTW, when you say implementing Self on Java, do you mean Self in Java or Self on top of a Java VM ?

I could be wrong, but I think that the current version of JSelf is an interpreter written in Java but that there were plans for a future version that would compile Self to the Java VM bytecodes.

That reminds me of something else. I need a way to access Kansas (the Self GUI) from across the network. This is not possible for the Mac version, but I will be using Sparc so simply installing an X Window server on the client machine (confused yet?) would seem to solve my problem. Except this network goes through a 33kbps modem so it would be too slow for practical use.

Since VNC (http://www.uk.research.att.com/vnc/) is often mentioned as a lightweight alternative to X, I was considering implementing a vncWindow object. This would allow Kansas to be multiuser on the Mac as well, which is a good thing. This problem is that VNC seems to be optimized for high speed networks (it transfers compressed bitmaps) and not modems.

An alternative would be to create a remoteCanvas object that would talk to a counterpart written in Java (which is where Morphic in Java comes in) and running on the client. It should transfer less bytes (send the info that we drew a green circle, and not all the bits of the circle) but I am afraid that I am just creating X all over again.

Does anyone have any experience with these things? -- Jecel

------> No: much of the stuff on this group is way above my head. But, I've read that the Berlin Group (who they?) are about to launch a windowing equivalent of X11 which should be lighter and faster. After all, for all its wonders, X11 imposes a pretty heavy memory overhead. It might be worth finding out more before going out and re-inventing a wheel for something else. I'd love a self with gui for my Linux box. (Ideally using GTK!)
