I tend to think Durmstrang probably takes half-bloods.

However, what we do not know is the geographical range covered by the 
school. Based on the comments we hear about the surroundings there, I 
do not believe it is in Bulgaria, but someplace considerably further 
north. So it accepts students from more than one Muggle country, it 
would seem. And if Russia is one of these Muggle countries, Durmstrang 
is starting from a Muggle population base several times that of Britain 
+ Ireland.
