I'm porting UbiquiTalk to Squeak 4.1 and running into a problem. I've been talking to Noury Bouraqadi about it and am posting the progress here in case anyone has any input. I'm attaching a screenshot, and can provide the images, but right now the load process is not documented. http://forum.world.st/file/n2400261/Screen_shot_2010-08-30_at_August_30%2C_2...

Noury, thanks for the reply. I loaded it in Squeak 4.1 and copied the image. Now I have two images running side-by-side. What happens is that the first one to be started sees itself in the host list. When the second one is started, the first one reports the error I told you about below, while the second one doesn't see either host. I've attached a screenshot. The only clue that I have is that RSTBroker>>objectFor:ifRemote: has a comment that says "answer a proxy if the reference points to other VM, otherwise answer the 'real' object" This sounds wrong because I still want a remote object even if it's another image on the same VM, don't I?
p.s. 42 out of 43 tests are passing (except UTMulticastSocketTest>>testTimeToLive)

Hi Sean,
I'm not sure to understand your problem. So, I'll try to clarify some stuff, hoping it'll cover what you need.
To use UbiquiTalk you're supposed to have multiple images running. Each image named host, should have a different name or should be running on a different device.
On every UbiquiTalk hosts gui, you can see the other images (hosts) on the network. When you click on a host name, you'll get the list of available servers.
We didn't try UbiquiTalk with Squeak 4. So, I'm unsure whether it works properly.

Hey, in preparation to port to Pharo, I loaded UbiquiTalk in Squeak 4.1. It appears (per the GUI) to be running on two images, but when I turn on ubiquitalk in the second image via the gui, I get an error message:
RSTObjectNotFound: host2
from RSTBroker>>objectFor: aRemoteObjectID ifRemote: aSelector
Any ideas?

Hi Sean,
Each images should use a different port. For instance, you can put 6667 ou 7777 in the second image.

Okay, we're getting there. Now the first image started shows both hosts and I can "run" the "Remote Workspace" service. But, when I doit in the "Remote Workspace," the code is run on the local image. The second image shows nothing in the host list still.
The code to load successfully in 4.1 is:
Installer ss project: 'KomHttpServer'; install: 'DynamicBindings'.
Installer ss project: 'KomHttpServer'; install: 'KomServices'.
Installer ss project: 'SPDProjectUpdates'; install: 'rST'.
Installer ss project: 'Keymapping'; install: 'PTabBarMorph'.
Installer ss project: 'OSProcess'; install: 'OSProcess'.
Installer ss project: 'SPDProjectUpdates'; install: 'UbiquiTalk'.
Installer ss project: 'UbiquiTalk'; install: 'UTAllServices'.
Then DoIt: UTHostMainGUI openInWindow.
I'm thinking from what I've read in the process that maybe it's not intended to be used for two images on the same computer. Is that correct?
Sean
The updated rST and UbiquiTalk versions now live in their main repos (thanks to Noury for access). The installation script is now:
Installer ss project: 'KomHttpServer'; install: 'DynamicBindings'; install: 'KomServices'.
Installer ss project: 'rST'; install: 'rST'.
Installer ss project: 'Keymapping'; install: 'PTabBarMorph'.
Installer ss project: 'OSProcess'; install: 'OSProcess'.
Installer ss project: 'UbiquiTalk'; install: 'UbiquiTalk-Utilities'; install: 'UbiquiTalk-Kernel'; "depends on utilities" install: 'UbiquiTalk-Cache'; "depends on kernel" install: 'UbiquiTalk-GUI'; "depends on kernel" install: 'UbiquiTalk-Plugins'; "depends on kernel" install: 'UbiquiTalk-PDA'; install: 'UbiquiTalk-Property Editors'; install: 'UbiquiTalk-Tests'; install: 'UTAllServices'.

p.s. I'm still not sure how functional it is, but it loads

Looks neat
Is this the project you are going for?

UbiquiTalk is an open P2P platform that supports automatic peer discovery without requiring any infrastructure. Hence, UbiquiTalk can be used either within a network infrastructure or an adhoc network (e.g. Wifi).
.... UbiquiTalk has been implemented on top of Squeak. It relies on rST (Remote Smalltalk) for remote message sending. Regarding host discovery, We used IP Group Multicast. Therefore, UbiquiTalk can be used through the Internet.
