Yep! But realistically I'm just one dude with a home network and a few VPSes doing BGP. How many /48s do I need? I was experimenting with traffic engineering so I did announce some /48's out of the /44 but that got old pretty quick.
Well, if the VPSes are in seperate sites, at least one per VPS, which means at least 2, which means that according to allocation policies, at least a /44. :)
