WebORB might be a good choice for your middle tier. Its like LCDS but supports languages other than Java. It also has free versions that I believe are only limited by the number of concurrent connections, so it might be ideal for your pilot phase. I have heard great things about both the product itself and the company that provides it from colleagues that rely heavily on it.
