restricting macros access to a single ooBase document?

[bjbev]

I have an oo Basic macro within an ooWriter template which accesses data stored in ooBase.

To avoid replicating the macro in the writer documents created from the template I have moved it to a library and intend to execute it from the ooBase document which contains the data. I would like the macro only to be accessable from this ooBase document. This doesn't seem possible with libraries. Is that correct?

Also, when I copy the library to my clients computer, must I instal it under each users documents and settings directory? It seems a bit messy I would prefer to keep the installation under a single application path.

Thanks for any advice ( or directions on where to look).
