Andrew registered a second level .PRO names with Encirca.biz, only to be disappointed by the fact that they do not allow him to use his own nameservers.
However, as far as I understand the second level domains are not unrestricted, so he might be in for a second surprise:
Quote from http://www.registrypro.pro/products/overview.php
Registrants
who provide multiple professional services (e.g. legal and medical
services) are eligible to register a resolving second-level name (e.g.
companyname.pro). After purchasing
and qualifying for two third-level domains, in two distinct professions
(e.g. name.law.pro and name.med.pro), registrants may request their
desired second-level name. Each resolving second-level name is
issued with a digital certificate and each registrant will have the
choice of an SSL or email (s/MIME) certificate.
[Update]: I just
looked into this a little further, and while it looks like Enrica
bypassed the above rule by registering the names with their own whois
information, their rules still pass the obligation on to the registrant:(from http://www.encirca.biz/html/terms.shtml)
Applicant represents and warrants that it meets the applicable .Pro
registration requirements within the Jurisdiction and agrees that,
during the term of the registration, it will continue to meet such
requirements and that it will promptly notify the Registrar if it no
longer meets such requirements.
[...]
Applicant acknowledges that if, pursuant to the performance of the initial verification services or annual verification services, Registrar determines that Applicant does not meet or does not continue to meet the applicable .Pro registration requirements, Registrar shall be entitled to retain a processing fee of $200.00 in connection with the performance of the initial verification services and $200.00 in connection with the performance of the annual verification services.
