Geronimo Features.

[Manu George]

Hi,
       I have a few doubts about geronimo features. I checked out the release notes from M4 but would like to know if there is any document listing the features added upto now. Specifically I have a few questions
       1) Does Geronimo have datasource failover capabilities like in JBOSS?
       2) How many connection managers does geronimo support? Can custom connection managers be plugged in?
       3) Geronimo does not yet handle drivers that supply their own DataSource,Is this statement still valid? How many types of datasources does geronimo support?
       4) Can you connect to RDBMS's that have not yet implemented JCA-JDBC drivers in geronimo?

Thanks
Manu
