Duncan,
Thanks, I am still searching and have just forund thsi (pdf format you'll
need acrobat)

This seeems to use a hose with holes in it rather than a tap. As I only need
to water a dozen plants all in pots I'd rather have a tap like system.

This is what I suggested to another contributor earlier, however as I
understand it the "normal" tap driven drip systems require a much higher
water pressure than is usually attained by a waterbutt. Unless you can
hoist
the waterbutt onto your roof of course !!!

Has anyone seen a drip feeder that can operate from a water butt? Is it
possible to use the "standard" fittings designed to run from the mains?
If
the "standard" ones are used I guess that I would need some kind of
adapter
to fit on the water butt tap.

This would make an ideal "water the greenhouse while on holiday"
solution.
