why not go for switch mode regulator?
I'd love to do that. Our assembler is currently checking availability and price on a couple of parts, including the EUP3410 and EUP3452A on this page: http://www.eutechmicro.com/PL_9_11_EN.html
If it turns out I can go switchmode for a minimal impact on BOM cost (and it fits!) I'll do it.
