Hola Roque,

no he seguido muy de cerca este ultimo tema que mencionas, pero creo 
recordar que en otras regiones solucionaron esto dejando a discrecion 
del ISP si poner o no en el WHOIS los datos de los clientes finales, 
por lo que no me queda claro que esto sea un problema grave, pero como 
dije no estoy muy puesto en esto, asi que si me podes corregir...?

saludos, marcelo
