Again, a slippery slope argument and an inductive argument are not equivalent. There's a reason the words are different.
A quick scan of recent media seems to argue differently: there are numerous uses of the term "slippery slope" by politicians arguing against the Patriot Act, for example, who argue that it makes it easier for future government power grabs. This is, by your terminology, an inductive argument, but widely referred to as a "slippery slope" argument by those actually making the argument. A typical phrase is "this starts us on a slippery slope towards...". Opponents of the recent partial-birth abortion ban act have made similar arguments, that this is the first step towards further restrictions on abortion.
For a rigorous treatment of the legitimate use of slippery slope arguments in their numerous forms, see "The Mechanisms of the Slippery Slope", a forthcoming book by UCLA law professor Eugene Volokh, available online in draft form: http://www1.law.ucla.edu/~volokh/slippery.htm
