Hey Leif,

I haven't personally used ehcache but am aware of it.  For 2.0 I'm 
personally going to use Terracotta for replication/clustering because it 
doesn't incur the requirement that the object be Serializable (which 
some of the classes we have to use are not).

That said you can certainly use Spring to configure a metadata provider 
that uses ehcache if you want.  OpenSAML itself doesn't use Spring, but 
if you look at the Shib 2.0 code  (in shib-common check out all the 
stuff under *.config.metadata.*) you can see that I'm using Spring 
create metadata providers (via a Spring 2 custom schema).

So, I think you with a reasonable approach you could create a metadata 
provider that took an ehcache CacheManager.  People deploying in an 
environment with Spring could then do what you suggest and others could 
use whatever other mechanism they had available.
