You can create any subdomain you desire. Most registrars even have a simple
interface to do this in a matter of seconds. No seperate registration is
needed, just a DNS record. You won't explicitly own 'www.domain.co.uk'
though, you probably own 'domain.co.uk', 'www.domain.co.uk' is already a
subdomain.

Yes, you can, but usually it would be http://hello.domain.co.uk rather than
http://www.hello.domain.co.uk

Google "subdomain"

Usually it would indeed. There's no objection against
http://www.hello.domain.co.uk however.
Accordeing to wikipedia (I'm to lazy to check it against a real resource):
In theory, this subdivision can go down to 127 levels deep, and each label
can contain up to 63 characters, as long as the whole domain name does not
exceed a total length of 255 characters.

Given that the limit of the wole domain name is 255 characters (presumably
including the dots), the only way that you could have 127 levels of depth
would be if each component was only one character long. (Well, acutally,
the final component could be three characters long.)

Perhaps using DNS wild cards you might be able to get longer though. Say,
you set up a DNS rules "*.example.net A 123.45.67.89", then perhaps that
would allow some really long over 255 character subdomain name to be used?

Actually, no -- I've just tested that. I have a wildcard on goddamn.co.uk,
so sfgdzsfgsdf.goddamn.co.uk, asgfasdfjashedfi.goddamn.co.uk and so forth
all work. You do hit up against a length limit. (At least Opera,
libwww-perl, ping and /usr/bin/host all do.)

But it's a PITA for the users. Harvard's website does that and it
drives me crazy (for example, the directory is
http://www.directory.harvard.edu instead of
http://directory.harvard.edu)
