A quick question for all of the Brits here:

I just got back from an interview for a job that would be located either in NYC or London (I'd say I have a reasonably high chance of getting an offer). The advantages of a London posting would be that my wife could probably keep her position (she currently works in the US office of a Cambridge-based company), so it's something I am seriously considering.

I was hoping I could get a sense of how doable such a situation would be - is the commute manageable (either London/Cambridge or from some point in between)? Is reasonably priced housing at all available? How expensive is decent childcare?

Essentially, uprooting the family would need to be worth it, and I suspect the pay will be okay but nothing spectacular. I'm trying to get a sense of whether this would be a reasonable financial and professional move - certainly the job is interesting, but I hear that London isn't cheap, and the distance between the two cities seems a bit daunting for a regular commute. I'd greatly appreciate any thoughts you guys might have.

Also - have any US expats worked in the UK before? Any ideas on how taxation/etc. works out with the US/UK tax treaties? I seem to recall Loki spent some time there, and there might be others...

I should probably look up their extradition treaty as well.
