Carlos, Bill y resto de la exquisita audiencia,

Quisiera aportar el trabajo realizado por un consultor del BID allá por
Diciembre de 2003. Seguramente muchos de ustedes lo conocerán ya que para
confeccionar este informe o proyecto ha transitado por muchos de los países
Latinoamericanos y aprendiendo en cada uno de ellos como están constituídos
los NAPs en nuestra región.


Dos comentarios al respecto: Seguramente contiene errores, como todo trabajo
de investigación, es dificil encontrar la perfección y objetividad total.
Por otro lado seguramente está desactualizado por tener poco más de dos

That's the feedback I've been trying to receive during the last two years
since I wrote the paper!!!!

Thank you, thank you, thank you.

I have no other response than really commiting to a careful review of your
points. At the moment my time is devoted to other activities. But Internet
interconection is really the subject of study I'm focused on and I expect to
produce a new paper by the end of the year. Before that I certainly will
exchange a mail or two with you about the subject.

In the meantime:

a) Sorry for ignoring this I'd never seen distinct definitions for IXP and
NAP, would you point me to some referencea?
b) There is a full list of references at the end of the paper for sources
about actual NAPs deployed, but gime me a couple of weeks and I'll give you 
more detail. I'm glad to see interest in maintaining an updated list.

Best Regards
