Yes. Generally, don't share working copies.

There is one thing I would mention here: You are making obviously important
modifications without version control. Yes, even though you use SVN, _your_
numerous changes aren't versioned!

Solution A: If you can't change the repository because it is an upstream one
you simply don't have access to, you can still create a local repository and
import the upstream sources as a vendor branch. The documentation actually
covers this use case.

Solution B: If you can change the repository but you don't want, because your
changes aren't stable yet, you should create a branch. When eventually done,
you can then merge your changes back to trunk. It also makes it easier for
others to read and understand your changes when they are in small, separate
pieces if possible.

That said, don't share working copies. However, that first requires that you
have a repository that you can change in order to propagate changes between
the working copies, and for that either of the above two solutions work.

Good luck!
