On another forum, I recently read that Vodafone UK are now selling inexpensive 3G femtocells that users who live in poor coverage areas can use, providing that they have a decent broadband connection (1Mbps).

The one off cost for the hub is as little as 50GBP (58 Euros) if you are on the right UK contract or 120 if not. I think a while ago I read about other providers selling these in other countries, but I think the costs were significantly higher.
My question is whether there are implications of taking one of these abroad in order to make a local network of your normal home cellular network but in another country! Like UMA, this could obviously be very useful to people who have a second home (or home-office) abroad. Of course, I am assuming that the Vodafone branded hub only works with Vodafone UK, and also that it is likely to have some form of UK IP address filtering. However, there are good ways around the second issue at least. Any thoughts?
