Request for comments on python distributed technologies

[Carl J. Van Arsdall]

Hey everyone, another question for the list.  In particular i'm looking 
for comments on some of the distributed technologies supported in 
python.  Specifically, I'm looking at XML-RPC, RPyC, CORBA, and Twisted. 

Before you offer any comments let me talk about what i'm doing a little 
bit.  Right now I'm creating an execution framework.  The framework aims 
to allow users to create a modular system by which engineers can 
mitigate some of the issues seen in large complex systems.  By using 
modules the system hopes to allow the system to change but allow 
engineers to re-use as much code as possible.  By using the modules in a 
framework we hope to encapsulate the entire system to that it is 
controllable in the sense that we can generate and catch errors anywhere 
in the system and exit gracefully, things like that.  There's a lot more 
to it but the motivation spawn from our system where the system kept 
needing to adapt to support changes in our company.  These changes over 
time have resulted in a large number of "hacks".  The hope of the 
modules is to make the code a lot cleaner and organized so that the 
system can operate in whatever way it needs to without having so many 
hacks.  This system I use also operates in a primitive distributed 
environment.  Currently, these are ssh calls to other nodes that then 
execute other python scripts and shell commands.  This is the next piece 
I'm interested in moving away from.

With all that being said, I've come across those four technologies so 
far and I've been looking into them.  I was wondering if anyone had any 
comments, pros/cons, or suggestions of other distributed technologies to 
take a look at.  I intend to integrate the distributed technology 
directly into the framework making it easy for developers to distribute 
tasks.  Anyhow, any comments would be greatly appreciated!  I also hope 
to release this framework as an open-source project when its finished, 
so again I community input is important.

Thanks!
