http://www.nexusmods.com/oblivion/mods/45861/?- seems to be a possibly remastered version of Illiana's Elsweyr - Deserts of Anequina. Is this one really legit, I know she has been very adamant that her stuff shall NOT be put back on the Nexus...

Yeah not sure about that either. I left a message with Leonardo over at The Assimilation Lab. My understanding was that Leo maintained the only legitimate upload site for it.
