You can find similar and much more enhanced implementation of caching solution A.K.A DataGrid through GigaSpaces

It comes with built-in partitioning, SLA driven container, support for Spring, SQL query support etc. A totally free community edition is also available which support basic hub/spoke clustering, persistencey etc.

And there is a .net implementation available as well.
