I've got a client moving to an NBN area (lucky bastards) who do *a lot* of uploading. Lots of remote backups (100GB+/week) and uploading videos on a regular basis. Basically any increase in upload speed they can get is awesome. 40mbit is fantastic, but more the better and with the NBN you can get 4x 100/40 connections to a single premises. I was wondering if there's a good way to take advantage of that upload speed by load balancing or bonding the 4x connections? (e.g: Exetel, TPG, Internode, Primus). I haven't really thought about it before, so don't really know where to start. A bit of googling tells me that maybe a bonded VPN type setup would work well? Anyone ever done this before? Mainly just fishing for ideas for further research.
