Leaking coolant from bottom of engine

[VX KAT]

~Just started dripping 2 spots on garage floor, size of nickel each. car sitting level.
~spots were dark brown/charcoal color, not oily (but not green)
~reservoir is exactly midway between min/max. Marked with grease pencil just now (as Bart did)
~"Appears" to source back to bottom of antifreeze RESERVOIR plastic container. leakage is seen coming from under plastic reservoir and rolling down metal parts there.
~Metal area directly under plastic reservoir shows leakage/gunk in all directions. Not that crusty like Bart's pics of green AF, looks moist, almost like oil, but not oily.
~Haven't checked the many other places suggested in that thread as most obvious appears to be the reservoir unit itself at this point.
~Radiator fluid is green, filled to top of radiator cap. Fluid in reservoir also green
~Thin Hose from reservoir to radiator shows no leakage or gunk at reservoir end.
~no smell of AF in cab or under hood (???)
~Ldub, no leakage from areas with 3 red arrows you showed in post of 12/3/06...BTW how the &#%@ did you get your engine so clean...looks like you could eat off of it....
~Haven't squeezed any hoses yet like IndianaVX suggestd to see if I can see it squirt
~no off-roadin', temps around 62 day/42 night
~if fluid in radiator is contaminated, how would I tell?
~Going to get radiator flushed ASAP (was going to get it done soon anyway...)

Think the actual plastic reservoir is leaking since the leakage is kind of broad from under it ?

Here's pics:
