A year later when we declared "alpha", Subversion was already being used by dozens of private developers and shops for real work.After that, it was two more years of bugfixing and stabilization until we reached 1.0. However, if the client and server versions don't match, certain features may not be available.Different versions of Apache can happily coexist on the same machine.
In other words, you are free to download, modify, and redistribute Subversion as you please; no permission from any company or any person is required. It is mature software, with strong compatibility guarantees.
Writing programs to access the repository is similar to writing programs that use other filesystem APIs.
The main difference is that this particular filesystem doesn't lose data when written to; old tree states can be retrieved as easily the most recent state.
Remember to take in account other applications running on the same server; for example, repository browsers use resources too, independently of Subversion itself. It comes with a command-line client that uses them.
In general, you can expect to need much less server memory than you would for comparable CVS repositories. There are two different Subversion server processes: either svnserve, which is small standalone program similar to cvs pserver, or Apache httpd-2.0 using a special mod_dav_svn module.
