DG,
if you are using webM release mechanism to move the code across servers and install the release, then you don’t have to reload the package.
if you are manually copying the flow.xml and node.ndf files, then you have to reload the (whole) package to have the new service in effect.
you may want to have a re-look at package management to overcome this problem; implying have similar group of services in a package (rather than one big package serving multiple functionalities).
