Answering my own post again.

I got the annotations for OneToOne and OneToMany to work bidirectionally 
across two different databases with different JDBC drivers using 
NetBeans 7.1 Beta and EclipseLink 2.3. It appears to be quite fragile as 
I got numerous NetBeans internal errors until I got everything exactly 
right. If someone is interested, I will put together an outline, but for 
someone more familiar with the way annotations work, the Sun Eclipselink 
pages on composite persistence units do point the way. It is very new 
and I suspect some aspects will change as more development is done, so I 
am not sure we are going to adopt this just yet but it is possible to do 
and does seem to be the in the future of JPA.

Also we have done no testing on using these annotations to actually 
update databases.

Again, thanks to all who posted comments.
