Your best bet might be to set up 3 proxies and have each of the Mechanize
clients hit a different proxy (using set_proxy for each instance) which
would push each request to the proxy's assigned server.

Something nice and simple like this should work (
http://github.com/igrigorik/em-proxy/blob/master/examples/line_interceptor.rb)
- you would need 3 changes to this file

1) Obviously line 3 needs to have a different port for each of the proxies
2) Line 4 would need to point to a different ip corresponding to each of the
three instances of inventory.b2b.com and the port would be 80 obviously
3) You don't want any substitution here so line 12 would simply be resp

In theory that should push the requests to the appropriate server for you
without a huge amount of work. I think you'll find em-proxy extremely
flexible in terms of getting this task done for you. As with anything that
messes with network traffic - there is some overhead - but you seem much
more concerned with concurrency than milliseconds of delay.
