	I will encourage you to participate in this project, we are very interested in researching connectivity patterns and delays in the region. If you see the probe's list we need more of them in LAC.

	In LACNIC we are hosting a probe, it was quite easy to set-up in a VM. If any one is interested in hosting a probe we could assist with our experience in setting it up (Carlos has the details of the VM, I do not know but I imagine that we could even find a way to share it).
