Give me your ladder points!

I was always a fan of WC3 Dota customs so this might be pretty cool, but it might have come a bit late. With valve producing DOTA2 and other games like League of Legends and HoN out there I wonder if there will be much of a place for this. Also wondering if valve owns the name DOTA now will they be able to sue Blizzard over this? Maybe someone with more legal knowledge can answer me below =) But anyway what do you guys this of this?
