it can yes. Actually you could make a script to automate the re-packing 
of all our depencies, without having to point to springsource ones. The 
main thing to remember is the main jar you are wrapping must be 
unzipped, but just look at the jxls, smooks and mvel examples I did to 
see what i mean. PaxConstruct attempts to help with this automation:

Geoffrey feels we should differentiate the repackaged bundles by a 
classifier and not by an artifactid prefix.
