I don't see anything particularly GPL-incompatible in there; looks pretty
much like a BSD-style license to me. Something that precludes SVN's use
by GPL'd projects, or precludes integration with GPL'd projects, is
something I'm sure CollabNet and the developers on the mailing list would
love to know about (along with all the Apache folks, since it's really
their license), considering that there's already at least on GPL'd
front-end for Subversion (gsvn), and plenty of GPL projects being hosted
in Subversion repositories.

(Not meant as a flame, please don't take it as such. I'd really like to
know where the Apache/Subversion license is "GPL-incompatible".)

Lacking an on-disk format that's actually useful for storing more
information than files and diffs, they invented one. I don't blame them.
The fun part, of course, is that svn is architected such that bolting up
to another repository storage system (say, an RDBMS, or even, horrors, a
bitkeeper-compatible SCCS derivative) is really just a matter of writing
the code (with a few caveats, obviously, but that's the basic idea).

"svnadmin dump" will provide a dumpfile of the repository, which could
be translated into another format, if that were desirable. Again, just a
simple matter of coding. ;-)

Not everyone is aware of this, but there's a new access method for svn
repositories that works with SSH, or as a standalone pserver-like scheme,
called "ra_svn". Translation: you no longer need Apache 2.0 and mod_dav
to access a Subversion repository; you just don't get some of the cool
features that using Apache gives you (such as all the access controls,
the availability of the repository via DAV and through a normal web
browser, etc).

This came about only a few milestones back, so it's not surprising that
everyone hasn't seen it yet. :-)
