[svlug] Rsync across SSH & alternatives

[Zachary Hanna]

I would recommend 
http://www.megapath.com/vpn-security/mpls-site-to-site-vpn/ if you don't
want to maintain the VPN yourself and if it's in the organization's budget.
They are pretty good about maintaining the performance between sites,
especially if you use them as the connectivity ISP at all the locations as
well as for the VPN. Then they can route it across their own backhaul.
