I'm unsure if having a 'vegetarian' option is the best way to go since there are about 40 different forms of vegetarian (I have been one for 15+ years). Maybe a better approach would be the ability to exclude ingredients and groups of ingredients. To me that solves a much bigger problem that I frequently have...I have three ingredients, but don't have the one that is generally required to go along with them (ie, I have olive oil, lemon, and garlic, but am out of basil).
If I can put in that I need a recipe without basil and without a category of meat or animal products (however, honey and egg are fine), that makes this infinitely more useful. If I can save that preference, that's even better.
