All the reading I did last night pointed to only 4 methods: boiling the alcohol off, freezing it off, vacuuming it off, or reverse osmosis.
Freezing it wasn't a very commonly mentioned method ad I would imagine it is because freezing large containers is generally quite hard due to the space required - I suppose a chest freezer would suffice.
Boiling it off seems to be the most common method but with the consistent drawback that it robs the beer of flavour. The way around that is to add the flavour back again after the boiling, or to add new flavours into the brew. I did read about adding a yeast afterwards but that an either re ferment and produce alcohol again, or continue fermenting after it is bottled, with predictable results in the storage closet.
The vacuum method seems to be popular commercially, although it is really just another way of boiling off the alcohol, just at temperatures that don't affect the flavour as much. The obvious drawback is the cost of the equipment and you still have to heat it.
Lastly, the reverse osmosis option will remove the alcohol, leave most flavour, and requires no heating or freezing or pressurised vacuum vessels, but it does require very specific filters.
In your situation the only real option is to boil it off, and I would suggest that as it's for your own consumption you work on finding a brew that has an acceptable taste after the process. I think most people are trying to de-alcoholise their brew to taste the same as the regular version, but with a slight adjustment to attitude that stops being a problem. As long as it still tastes good enough to drink and suits your palette.
