I would think the Hibernate usecase would be a good candidate for a
light weight version of Teiid.

Yes. We will not loose "embedded" configuration. Teiid can use
"JBossEmbedded" for this. If the "JBossEmbedded" proves to be heavy
weight then we need to come up a "profile" like "web profile" in
JBoss AS which does not contain unnecessary services like ejb, jms
email etc. This can be done later with out any changes to code.

Do not know yet, as they they do not have too many details on their
site. In those cases, we would either need integrate them from JBoss
AS
or stick to JBoss Embedded. This project sounds good, they have ways
go
in supporting features.

With the Connector API as before, you do have opportunity to wrap any
connections that you want handle yourself.

Thanks. Please do as this is a very important step and we want to go
in
the right direction.
