One idea is to have the shift or ctrl keys temporarily toggle "snap to pin" mode. Draw nets as usual, but just before you select the final pin, press and hold the shift key to go to snap to pin mode, select the final pin, then release the shift key to revert to grid (or no grid) mode.
This is an interesting idea. I seem to remember some general drawing package years ago (Micrografx Designer, maybe?) which, when drawing a line, would force it to perfectly vertical or horizontal if you dragged the second endpoint while holding down one of the modifier keys. This seemed very streamlined and supported the "one hand on the keyboard, the other on the mouse" way of doing things.
