RIPE Labs had an interesting article about filtering of /48 prefixes earlier

There's also a useful RIPE Labs article on general prefix filtering lengths

First:
But likely if you are in that camp, just asking for address space,
that you can use stably for a long time, from your network provider who
provides you connectivity is a better way to go.
Um, sorry I figured by the fact that I was posting on Nanog the context was

It's only a worry if you can only route /48s, which was my question. And
seriously, we're going to be banging around

lots of space to do nefarious things. that said. if you select your peers
carefully and don't mind
a bit of hand crafting, you can /96 and even /112
