According to wolfram alpha, it is zero.
We observe that:
infinity^(-infinity)= 1/(infinity^infinit)
Now, infinity^infinit must be considered to be quiet a lot. The inverse of this should be etremely small, i.e. very close to zero.
It's important to remember, though, that infinity isn't a number, but an abstract concept.
