dihydrogen monoxide is overkill, but carbon dioxide or co2, is analagous to h2o, so dihydrogen oxide would make sense.

And since oh- is the hydroxide ion, Hydrogen hydroxide is reasonable and analogous to potassium hydroxide, etc.

H2S is also called diydrogen sulfide.
And a yahoo search gave me this quote on h2s :

Synonyms include dihydrogen sulfide, sulfur hydride, sulfurated hydrogen, hydrosulfuric acid, “sewer gas,” “swamp gas,” hepatic acid, sour gas, and “stink damp.”

More than you ever wanted to know...

But the point is there isn't just one answer, and it stinks. ;-)
