As soon as you get the space, register it in altdb (whois.altdb.net).  
Some networks apparently filter based on the routing registries.  Then 
there are the clueless/non-maintained networks that filter based on 
outdated info.  See http://not69box.atlantic.net/ for more on that.

Not "the possibility"...the certainty.  If you don't have "old PI space",
you're screwed, because you're going to get tainted space.  Until all the
filters get fixed (i.e. likely never), it's probably a good idea to get a
/24 from your provider(s) even if you get PI space, and use a few
addresses from that 'old space', assuming your providers have some old
space they can give you, for backup MX and NS records.  It'll make
switching providers a little trickier, but not nearly as bad as if you
were entirely in their space.
