HowTo Copy one server commit to another one (without svnsync)

Hi!!

This is the first time post something here, wishing I could clear some
doubts or find some help.

My problem is this:

I have one main svn repository, which i use to commits changes, and
another remote one (provided by tuxfamily.org, which is like SourceForge).
Now I've dumped the main repository and applied to the remote one.
What i need, is when I commit on the main server, this commit should be
copied to the remote one. I can't use svnsync since i have to modify the
post-commit script in the remote, which i have no access to do it.
So, how i could do this from my server? (taking in count that I must do
commits on my server and not on remote)

Thanks in advance.

Cheers!
