BPEL Caching / Persistence

I recently attended a vendors presentation on some caching technology whereby Java Objects could be stored in an in-memory DB or caching layer. The architecture appeared to be quite sound in that it utilized a peer to peer network to manage copies of the information for reliability purposes. The demonstration sparked my interest in its application to stateful BPEL as persisting to a database is a costly exercise when executing large amount of transactions. Prior to / Following this I read subsequent articles at which discussed BPEL Reliabilty using such a concept. A reliable in-memory grid caching store was discussed:

The original article:

Article 1

A current article:

Article 2

Application of technologies such as these will provide dramatic impacts to stateful BPEL Services that are more and more being utilized for Service Composition.
