[integration.middleware] Carefully select middleware

If middleware must be used, consider this:

• Licensing costs for middleware is high, unless open source middleware is used.

• All development in middleware tends to be expensive.  At the very least they require a bunch of servers to provide failover.

• Good middleware developers are hard to find and will be even more difficult to find in five years where there is a problem.  

• It's hard to convince a well rounded Java programmer to become a middleware developer because it can reduce their range of skills over time (aka employability).

• You can accomplish the same solution using a generic java program without middleware cost.
