Benfrain,
I too am a HALO luva and while it may be theoretically possible to frig up a Intellifeed rig I wouldn't say it's a practical solution.
Batteries are a bind. But if you get good NiMh rechargable - I did quite a lot of investigating and Antsmann batts are the best and priced OK.
Otherwise, the HALO is pretty frugal with batts and they last a while. I just buy the bulk cheap Alkalines from superstores etc for £8 for 20 and they do just as good, easily last the day and I always replace batteries for each day anyway.
As for corkscrew - seems great on paper - but then so did the Titanic
