Thank you for your help, and your clarification about osgi specs. I wanted to install the same bundle several times to create several instances of a UPnP control point, and it seemed that this would fit perfectly for this usage, "isolating" the different instances into separate bundles.
I'm looking for a replacement solution. Thanks.
