[Zope] Zope products install

To install products , you need acces to the Control Panel and import directory. My Zope hosting company doesn't give access to these functions. (for security reasons I guess) On my home computer I also installed Zope ; could I install a product ( Zubb for example) , go to where the files have been installed and then copy the content of these files on the Zope hosting company server ? Would this work ? ( As you have probably already understood, I am quite new in Zope :-) Thanks for your answer. Henry
