Yes, that would help a lot. But I doubt if it is easy to change the hostname on production/live servers, specially if there are accounts on that.
Actually this is what we're currently doing - copy/read data from euk dns and put it in our private NS. Then set/request the client domain's NS to our private NS.
RIPE/ARIN will show datacenter's name in IP whois, that is no problem, since we do mention that the datacentre is Rapidswitch. In fact, it reassures customers when we point them to the datacenter
website hosting.
What I suggest in favour of reseller accounts in general is:
a) Setup a separate completely anonymous domain for reseller accounts, it could be owned by Rapidswitch.
b) set up corresponding nameservers for these reseller accounts
c) Don't mention eukhost anywhere not even in FTP banners or SMTP headers
d) if somebody wants to report abuse they can do so via your anonymous domain mail (standard contact info on root
website hosting of the box) OR via datacenter contacts.
If the reseller is good enough, you'll get more business from him (there is a scope of higher margin from you as compared to others). If he's not, then he's not worth being a reseller in the first place!
The above may already be there, but I'm not aware and in such case, you could ask while signing up if the reseller wants a anonymous setup.
Hope I'm not getting too deep.
