Note from Jose, on patching over work so far:
DWR-Spring-Scopes is easy if you forget about DWR scopes and stick to the Spring ones (singleton, prototype, request, session, global or custom). Now, singleton and prototype don't need AOP proxies. The others do. So you only need to include the AOP namespace if you include a scoped bean (that's not a requirement of DWR but of Spring really). In practice, this is not the norm (the gross of the beans should be stateless singletons).
IIRC you can use something like: <param-value>classpath*:blahblahblah</param-value>
