hwo to get feedback from remote nodes ?

Hi

Scenario:
I am submitting a description on Node A with sfHost as B. Internally, on 
Node A the description is parsed and passed to node B over RMI. The 
description on B executes and performs a number of tasks, like 
installing a program.
Problem 1:
SF on Node A reports successful deployment after it successfully 
transfers the description to B. If it fails on B, how do I get that 
error on A. in this particular case I want the stdout generated by 
install program. This output is available to the sfComponent that is 
performing installation on Node B, but how can I send this data back to 
parent node using smartfrog?
Problem 2:
On same lines is it possible to submit a description from on node to 
multiple nodes, in case I want to install same program on multiple 
machines. sfHost doesnt take multiple arguments and command line syntax 
also takes one machine at a time.

thanks for the help!
Sanjay
