Definitely can be done. Did it on my NP3 about a month ago. The thread I started to get some ST wisdom on this matter is here.
Steps:
1. Remove the fork and the plugs covering the plastic cup/well below the stem.
2. Remove all grommets from the top tube.
3. Route the brake cable housing from the back - ie from the saddle side towards the fork. You might have push it through to get to drop into the headtube.
4. Once you see the housing, grab it and route it up into the unused hole of the plastic cup/well in the headtube.
5. Drill out a larger hole in the grommet that goes into the top tube opening by the saddle. You can't really damage it, so drill away.
6. Route the brake cable. Route the cable housing through the drilled grommet and clip it into the hole.
Works like a charm!
One word of caution - be careful with the rear brake metal thingie that's used to attach the brake to the frame. I accidentally stripped the threads inside the frame on mine and had to do some drilling/epoxying to get a larger thread in. It was not fun.
Next races on the schedule: none at the moment
