I store edge based properties.  Each half-edge has a pointer to an 
"information" edge, which already can store selection, crease and seam 
values.

In fact, this is how half-edges "find" each other, is through the info 
edge (it has pointers to both half-edges).  This is also how manifold 
errors are detected; if you try to add a half-edge and it's info already 
has two half-edges in it, then you've messed up mesh manifoldness, and 
an error is raised.
