Yes I know those sites but I think this method is stupid as it has no benefit of the solution of rsync servers and it has the following disadvantages: - hosts are backed upo twice => twice more disk activity on the client and not cool for the user - if the file foo.doc is on 3 PCs in site A it'l be transferet 3 times to site B and only after that optimized by the pool which is stupid.
