I have a feeling you wouldn't get any support for such a feature from
the developers. This is a case where the svn client is insufficient
for your needs, so you would be told to go write your own client
program using the language bindings, which exist for most any language.

I'm primarily a PHP programmer too. You may want to look into this:
http://pecl.php.net/package/svn
Language bindings should be faster than running command line programs
and parsing output. But I haven't tried to use these PHP SVN bindings
yet. I ran into problems with the first version, but maybe this one's
better, or maybe I was doing something wrong before.
What do you mean "svn list [...] doesn't work"?
