I disagree, if there is only one *MAIN* building that an IXP is in then =
participants are going to have to go to that building, giving the colo =
provider the monopoly, which affects not just cross connects towards and =
IXP, but other participants too, that you might want to connect directly =
to.
Yes, if the IXP is distributed across more than one building then you =
have choice as to where you (and other people) put their equipment, so =
you may have to go to another building to connect to certain peers. =
Sadly nobody lives in a perfect world, so IMO having the IXP distributed =
across multiple buildings is better as you can connect to all those who =
are in your building directly, and peer with the rest over the =
distributed IXP.
