The "Multilingual multiuser multiblog engine" part of the site header should answer a few of your questions ;)

The answer to the rest is "yes" :D

Is it possible to have a demo of any site offering such ;)
Thanks

There's a demo available on the tabs at the top of the forum.

If you want to see a multi-domain blog then I might as well whore my own :D

If you want to see a multi sub domain blog then I might as well whore my other one :D

are just pefrect. I was wondering if users can register with there desired blog name and start blogging. For eg
abc.waffleson.com etc

Is it supported? Rest is all just perfect.

There is an [url=http://forums.b2evolution.net/viewtopic.php?t=8146]autoblog plugin[/url] that will "sort of" do that. On those blogs I cheated and have a *.waffleson.com setup in IIS which made the subdomain part a doddle.

I'm pretty sure you can do a similar sort of thing on a *nix box, but I'm no expert so don't quote me ;)
