Atmosphere sample return mission to/from Venus

In the April issue of Sky and Telescope, page 30, it mentions that there
is some unknown chemistry in some of Venus' clouds. Particles of
something coated with sulfuric acid. To say that there could be life on
such would be a really long shot bet, but a sample return mission might
be interesting to do. Though building and flying to Venus a return
vehicle that could get back out of Venus' atmosphere and gravity well
(and some of the Sun's as well) and back to Earth would be rather
difficult. It'd be pretty much the same size rocket you'd need to send
a small probe from Earth to Mars. And you'd need to ship that to Venus
all fueled up... This doesn't look too feasible...

Probably more practical to send a small remote control chem lab on a
blimp...
