> You don't order 10Gbps ports at various IXPs if your community run network can't deliver that bandwidth usefully.

Well, to be fair....

   - Membership of most IXPs is not that expensive and the smaller port sizes are not that expensive
   - Many IXPs are moving to 10Gbps as the default port size (e.g. with a membership at LINX in London, you get your first default-size port for free, which is now 10Gbps at LINX).
   - If you are running an eyeball network (i.e. xSP, WISP etc.) then you might as well just buy bare-minimum IP transit and save your money for your peering point memberships, since most of your traffic will be going to the CDNs etc. all of whom have open-peering policies at IXPs, so why pay more than you need to ?
   - Moving to cynical-view territory, its a marketing expense ... become an IXP member, get a nice logo you can put on your website and give your salesdroids something to name-drop ....
