R is an open source project, so providing ways for you to do this is not 
one of our goals.

If I were your client I would have asked for the source code for 
whatever you're doing; if your client isn't savvy enough to do that, you 
should provide it and explain why it is useful, and what your client is 
and isn't allowed to do with it.

If you think your client will steal from you, then you should find 
another client.
