Yes, they can. Any service that's published from a bundle in an unscoped plan will be available globally.

You can't add a single new bundle to a plan at runtime. However, you could update planA to include the extra bundle, and then hot redeploy planA.
2.I have already deployed planA with some bundles. Using hot deployment can I add one more bundle to planA?
Yes, it will. Take a look at the shared services war in the latest version of the Formtags sample for an example of how to use ServerOsgiBundleXmlWebApplicationContext in an RFC 66-compliant WAR file.
3.Also once you migrate to RFC 66, will ServerOsgiBundleXmlWebApplicationContext support still be available?This can help the web-application to access the OSGi services.
The migration's already available in the latest nightly builds and will be included in the M3 release of dm Server 2.0.
