This comes up quite a bit, they are similiar in intent but quite
different in execution.
- HiveMind has a very sophisiticated configurations model (very
similar to Eclipse plugins) based on configuration points and
contributions (from multiple locations)
- HiveMind is the infrastructure for Tapestry 3.1, and many Tapestry
applications also use Spring
- Because Rod and I (and the other Spring team member's I've talked
to) want to foster cooperation and compatability rather than
competition

I must admit I haven't had a chance to get a good look at HiveMind, but my understanding is that it is a DI container that provides service wiring and interception, much in the same vein as the Spring Container. From the outset the two containers seem to be mutally exclusive rather than complimentary.
