I'll investigate further.  Right now I'm working on the ViewState issue.

Thanks a lot, Seb.  I think I spent too long pouring over the docs, mailing 
list archives, wiki, demos/examples and stfw.  I wasn't seeing the pattern of 
how the relevant JMeter functionality ties together to solve the problem.  It 
really helps to discuss this with someone who groks JMeter.  I'm a lot 
clearer on things now.

I'll let you know how I progress with this.
