    Policy Proposal 2003-11 at ARIN may end up reducing from /20 to /22 for multihomed organizations.

    But regardless, getting a /24 is not hard. Ask your upstream. Your upstream provider assigns you a /24, not your regional RIR.
    Your RIR will only assign you on bigger needs, i.e. /20 as you said.

    Get on route-views.oregon-ix.net and see to yourself how many /24's are existing on internet routing table, not to mention how many of them are from North America, especially USA.
