We have a company we work with, in the US which hosts a SVN server. We prefer GitHub in Australia. We would like to sync between the two if possible. i.e. The US team will keep using SVN, and the Australian team will use GitHub. Possible not syncing all of the files in the SVN, as it also contains binaries of the source code. It would be good if it can be accomplished without installing any software on the US SVN server. What are the options and the pricing.
