Maybe you should just apply and see what happens? Why are you coming to an apparent foregone conclusion and then actively trying to make it reality?
Remember what Henry Ford said? "Whether you think you can or can't, you're right."
Also, if you look at the list of things YC actively say they are interested in, you'll find that it's far larger than just social media, mobile apps and HTML5. http://ycombinator.com/ideas.html
Oh, we applied to Y Combinator, I should have made that clear. I'm just trying to evaluate our chances, and seek out other opportunities in case YC doesn't pay off.
Good luck on the application!
Are there Y Combinator like environments for high tech startups working in other spaces? (ediscovery, in our case.)
I don't know of any that specialize in ediscovery, but there are absolutely other "YC'ish" incubator type programs, of various types, around the country. Somebody was compiling a list a month or so ago, search the old posts a bit and you can probably turn up that post.
mindcrime is right - whatever you focus on will come true. your biggest enemy at this point is negative belief. Lots of 30 and 40 year olds start startups and do very well.
stop talking to your negative friend - people like that are to be avoided like the plague.
You should be first getting a lot of insight and then applying. If your state of mind while applying was similar to what it is now you might not be able to put together the best pitch.
