IPv6 prefix lengths

Hi all,

What IPv6 prefix lengths are people accepting in BGP from
peers/customers?  My employer just got a /48 allocation from ARIN, and
we're trying to figure out how to support multiple end sites out of
this (probably around 10).  I was thinking about assigning a /56 per
site, but looking at the BGP table stats on potaroo.net [1], it looks
like this is not too common (only .29% of prefixes).  Thoughts?

Thanks,
--Richard
