In reply to Edradour:
People often ask for advice about the best way to do something, only to get replies that suggest doing that thing might not be a good idea at all. I don't see this case being any different.
I'm not trying to make a big issue out of it, but I simply gave the answer that I'd give to Gav if he asked me the same question in the pub, with absolutely no malice intended.
I'd give a similar answer if someone asked "what's the best barbecue to use inside a snowed-in mountain tent?"; "I don't think it's a good idea".
Apologies to Gav if I've caused offence.
