Not sure if you made any progress but I followed the tips on Modaco and rooted my Hudle in two pretty simple steps:
1. Download the ADB driver installer
2. Download Kingo root app
3. Run ADB
4. Connect Hudl to PC and allow ADB to update drivers
5. Run the Kingo app
6. Bingo! One rooted Hudl
I sincerely hope there's some dev work on this tablet but it's obviously going to rely on the UK devs. Would be great to get CM10.2 custom tablet rom!
