Can I not use svnadmin load with a remote repository?

My company has done a preliminary spec for moving from CVS to
Subversion, using the python script cvs2svn. The cvs2svn script works
fine, but when I try to do an svnadmin load of the dump file created,
using the Assembla https URL, it complains that it can't find a "format"
file.

After quite a bit of web searching, I think I see the problem. The path
for the destination of where to load the dumpfile contents seems to have
to be a file path, not a URL. Is this right? Or am I missing something?

Thanks!
