Nov 25 at 9:47 comment added KP Hart The definition does not work because of the "if and only if". If you weaken it to "The family of sets of the form $\{i\in I:x_i\in O\}$, where $O$ runs through the neighbourhoods of $x$, generates the ultrafilter $\mathcal{U}$" then the answer to question 1 remains the same but question 2 may get a more interesting answer.
