OSGi is fine for containing coursely grained services but avoiding
spring for configuration and assembly of these services is going to
make a *lot* of work.

i would go further. i would really like to avoid using a service at
all for configuration and assembly. (using a service to load services
would create a nasty design knot that would be better avoided.)

OSGi would allow services to be delivered as self-assembling,
self-configuring applications linked to each other by dynamic service
references (we use dynamic proxies for these initially). the
applications would be able to use spring, commons, hand rolled, pico
etc - whatever is most convenient.
