why not just use acidmods?
also, how will it handle special characters? ex. [,],',tm,etc,etc???
you could make it:
blog.acidmods.com/hop
blog.acidmods.com/name
also you could create permalinks..
shop.acidmods.com
forum.acidmods.com
tut.acidmods.com
dev.acidmods.com (for dev site)
rnd.acidmods.com
media.acidmods.com
news.acidmods.com
you get the picture..... most hosting offers unlimited sub domains!!! and if you set it up like that and there are any changes you wont have to worry about dead links...
just my $0.02
