I think I've found a good way for nade throwing
NOTE: PHP tags because code tags are currently broken..

   // get a rough idea of how high it can be thrown
   vecMidPoint = vecSpot1 + (vecSpot2 - vecSpot1) * 0.5;
   TRACE_HULL (vecMidPoint, vecMidPoint + Vector (0, 0, 500), ignore_monsters, head_hull, pEdict, &tr);
   if (tr.flFraction != 1.0)
   {
      vecMidPoint = vecMidPoint + (tr.vecEndPos - vecMidPoint) * 0.75;
   }
