He Martin-

	You may want to have a look at a rails plugin I wrote called  
BackgrounDRb [1]. Its built for this exact purpose. You can have  
worker classes that run in the drb server that you can start and stop  
from rails. It also has hooks and examples of how to create ajax  
progress bars while your workers do their task.
