[squeak-dev] inter-image communication and queueing suggestions?

I have not found any information on sockets in SBE or PBE. I will continue too look.
In my exploring, I thought JSON looked promising..pharo as a json server thingy that perhaps squeak could consume.
IIRC Stomp, which I have used previously on squeak has two side too, but I am not sure on this.

Hi Timothy --
If it is just a text stream, use sockets. If it is a data/byte stream ... well ... I am not sure whether the byte interpretation for structured objects is still compatible between Pharo and Squeak.
Maybe you could also use a file and two file streams, a writer in Pharo and a reader in Squeak, as intermediary ...

I have used ApacheMQ(?) and Stomp in squeak to communicate between squeak and a C++ application, it worked well, but I would like to avoid this for my project.
What I (will) have is a pharo image that will parse a large XML document for me (squeak has FileSystem incompatabilities that SAXHandler etc need) .
During a SAXHandler callback, I want to kick this to an image that will parse some data using a PEG grammar I wrote and that needs some automated testing to perfect.
Communication I would like is pharo (sax) -> squeak(xtreams-parsing).
Some basic reading showed rST from about 2005? as a possibility as well as Nebraska,which I believe has been removed from Squeak several releases ago.
I have used neither of them.
If there is not a method I can make work, then I will do pharo(sax/stomp)->ApacheMQ->squeak(stomp/xtreams-parsing), but I prefer a pure smalltalk mechanism.
I still have a textbook of mpq(?) queues from a course I really enjoyed and pharo(sax)->squeak(queueing)->squeak(xtreams-parsing) would be really cool.
thx in advance.
