i see Sedo/Namedrive parking more for sales, after all what can the parking services offer me than i cant do myself with my asian IDN when they dont even pay special attention to the markets im interested, i mean Japan or China? it is easier for me to get an account with japanese affiliates than to give them a high percentage of PPC just to "park" or should i say "to park for they to forget my IDN".
I guess if u dont have a few dollars more to invest in hosting, they are okay. just a matter of money.
another thing I intend is what another japanese domainer i met in a japanese forum is doing, i mean to hire chinese university freshman students to work on his sites, considering you can hire them paying like $200 per month (some greedy bastards pay them even less but im not such an evil person to pay $100/month), this will mean a cheap investment to have people working full time 8hours/5 days a week doing content as well as marketing my IDNs in many other chinese websites, directories, blogs, forums, etc. At this stage for me hiring students is better ROI than adwords focused to China for what i intend.
This japanese guy is doing great. i guess im gonna "copycat" him he he he

For what i pay registering a single and sometimes bad chinese IDN .com $8, i can have someone working all day in my many other good IDNs increasing their value.
