Allow scp upload work with multiple servers or multiple profiles.

I faced exactly the same issue as here:
http://stackoverflow.com/questions/4360958/maven-wagon-plugin-can-wagonupload-upload-to-multiple-locations

I would like to upload my jar to multiple servers using scp.
I tried configuring multiple profiles as stated in the answer, however upload plugins works only once for the last profile.

It is stated "or list" in the documentation for url parameter, but there is no example how should I pass sevral urls there.
