I've been asked by someone to link to a sites subdomains, but they say they have a few hundred subdomains, do SE class this as the same site? They also say the LINKS pages will be different on each subdomain...Hmm not from what I've seen already! eg. subdomain.site.com subdomain1.site.com subdomain2.site.com Hope you understand what I.m trying to say!

They show up as seperate domains in SERPs. However, they are VERY likely to be heavily related in terms of providing link popularity.
