Todd's mistaken.  I've multi-homed /16s that were pre-CIDR ("owned" by the
company rather than the provider), /23's that were pre-CIDR (same) and
post-CIDR /24's owned by various national and regional ISPs.  All it's
taken is contacting and contracting with both ISPs and getting an
Autonomous System Number from ARIN.  Most providers will even help you
with the ASN.  

I _flat_out_refuse_ to let anyone else own, access, monitor, or configure
my border routers, and other than the providers making sure I've got a
good BGP config, they've never seemed to be put out by the request to
advertise or accept routes based on what I'm allowed to advertise from a
different provider.  Back when we went through the exercise the first time
at my old company it wasn't that popular a thing to do as a customer, and
having a pre-CIDR /16 of our own made things go a lot more smoothly (as
did having T-3's.) The last time I did it, it was with /24's and T-1's 
from two completely different providers and it actually took less time to
get the stuff spun up on the second circuit and get the original provider
to accept an external advertisement for a netblock they originated.

I advise keeping the bandwidth symetric, loading the routers with memory,
and having a good test plan.
