a CX bike. Or vice versa?

Now that UCI allow disk brakes can you theoretically use a 29er in a UCI event, or do you also have to use drop bars?

I'm not saying that a 29er would be as good for "proper" CX but as Nick Craig has used flat bars on his 3 Peaks bike for at least the last two years, would a 29er be better for this style of "extreme" CX?

Not bothered in a real way, just a stream of conscience thing.

When its got 35c (now 32) tyres and bars less than 500mm wide.

Well I forgot to add the tyre width. So is the bar width a technical restriction to eliminate MTB bars?

as a regular rider of both 29ers and cross bikes, I can say that they're very different.

A cyclocross bike is much closer in geometry, handling, etc to a road bike than any kind of mountain bike.
discs or not.

mtb frames not allowed in the 3 peaks and Nick used flat bars as sram let him use their new flat bar groupset last year

Also the peaks is a cross race not an mtb race the same way Rossi can't ride his M1 in world super bikes!

I did ask this a few years back but the organiser (quite rightly) wouldn't let me ride it on a singular swift with cx thin tyres and narrow bars.

The Three Peaks is an entity unto itself and as such can allow or refuse entry to whatever bike they like. However, if we're talking UCI sancitioned races, there would be nothing stopping you using a 29er with drop bars narrower than 50cm and tyres narrower than 32mm. As for the 'true' character of each type of bike, I agree with Terra that they are quite different, though I do like to try and blur the distinction.
