Pretty much the only way I've seen a /48 split in practice is to get 256 /56 (one per site) then 256 /64 (one per VLAN).

/52 and /60 are quite common as well, predictably what with falling on a "letter boundary" and all
Interesting. I've only seen /60 when they're trying to split up a /56, and IMO it's a little unclean.
