Yes - but being a very open and fluid market, this is normally quick  
to arrange and inexpensive compared with organising capacity into a  
private colo centre that is not so neutral.

Yes, but depending on the structure of your network, at such  
facilities you can regularly attain settlement-free exchange of  
internet traffic with networks you have significant data to.

I'm simplifying to an extent - it is a little bit more involved model  
than dropping a server onto someone else's network and seeing what  
happens next, but if you have plans for significant traffic, or  
quality is a major concern, then the carrier hotel has much to offer.

Check out the customer lists of the big carrier hotels, there are  
plenty of voip, traditional tdm, and internet service providers listed  
- so it's working for most ;-)
