Ok, Sorry if I mess up your original question.
You really should consider making Extlib part of your Domino installations. ( it is IBM's way of shipping new features to xPages) If you are missing features in xPages you might find them in extlib.
There is an automated way of adding extlib to your servers. you simply use a plugin database and import the new versions. Domino will then automatically install new version when http task is restarted.
