I've noticed that http://www.nanog.org/filter.html is a little out of date, 
and I was wondering if anyone knows whether any ISPs currnetly have issues 
with /24 BGP advertisements for blocks outside of the traditional Class C 
space?

My regular analysis report shows 120790 /24s in the BGP table today. So
I'd suspect that there are few problems with /24 advertisements; but
that's just my BGP view, could be different elsewhere.

Before you start your migration, announce one /24 as a trial and see
what happens?
