We are building a services tier which will be based on ActiveMQ JMS, and our standard Resin webserver/app servers. We are building this with 2 nodes sharing each on the nodes. They will use a shared file system. We have a few services to start with, which are internal only at first. Should be interesting.
We are also working on some new products, and we are pretty close to selecting Endeca search for the indexing engine and SEO engine for it. More on that as we get along with development and implementation. The product looks pretty cool, so it should be fun.
