Fernando,
No doubt Amsterdam have good peering, but the American ASN (14907) is listed only on TampaIX, which is a poorly connected.
Thanks for your suggestions - they have always floated around, but there're many issues to resolve. First of all, peering traditions in US are completely different, than in Europe or anywhere else - especially if we're not a huge telco.
I suggest you ask a donation or buy transport from Tampa to Miami (Nota) and/or Atlanta (56 Marietta St). Both places are much better connected. From my POV (South America) Miami would be the best.
Getting to those locations doesn't mean immediately all South American providers will be peering (especially large telcos).
I suggest you ask a donation (network and Miami/Atlanta rackspace) to Sago Networks, they recently released their fiber backbone which should have plenty of free space: http://www.techlinks.net/CommunityAnnouncements/tabid/55/ articleType/ArticleView/articleId/181087/Sago-Networks-Completes- Private-Fiber-Network-from-Tampa-to-Atlanta-and-Miami.aspx
We've done really good research about all companies doing any networking activities in Tampa area. Sure, if there's a way for us to do more efficient stuff, we will do so eventually :-)
If you decide to go the buy route I estimate the cost of a 2.5gig wave to Miami or Atlanta would be around 5k monthly (plus cross-connect fees, taxes, rackspace, remote hands).
There're more issues involved - like our routing capacity, network engineering hours, etc. I'm not in any authority to speak about this, but really, if there're good things to do, we generally do them :)
BR,
