I used a LM3S8962 (or something like that) in a project last summer.
Loved it. Especially the way the pins are set to be either I/O or
a single peripheral function; too many times I've been unable to use
all the features of a CPU because a single pin would be shared among
multiple peripherals.

I think he is only asking for a single USB port, he just wants to be
able to use it as either a host or a slave. This part can do host,
slave or OTG! I am impressed with this part... especially at $9 for
1k qty. But... a 1200 page manual??? Wow! I guess that's why they
call it a system on chip!

How about the TI/Luminary LM3S9B96?

Appears to have only a single USB controller, but I think it
covers the rest of your list. Not sure how good the SDRAM
controller is; I think this is the first line from Luminary
to support SDRAM. They have a pretty fine-grained feature
table, so there may be several devices in the line that can
work for you.

and idle google for Cortex M3 SDRAM Controller pops up some new
emerging choices ?
["TI=92s new LM3S1000 Series additions augment the series with a
versatile External Peripheral Interface (with modes to support SDRAM,
SRAM/Flash, Host-Bus, and M2M),"]
& Fujitsu ?

It's the SDRAM that really pushes this into a corner.
- rather mutually exclusive with 'lower cost' ? ;)
Choices would be (maybe) NXP Arm9, Freescale various, or infineon
higher end ?

Is there such CPU that has SDRAM controller, USB host/slave, Ethernet
MAC, CAN as well as utility ADC and several PWM channels all in one
chip? The performance is not very critical; lower cost is important.
There are plenty of choices that have either (Ethernet + USB) or (ADC +
PWM), but it looks like none of them have both.
