Thanks for explaining.

Some of us here at Camptocamp have discussed this a bit further, and
we've come up with a potential solution to this issue, where the first
point to be laid down is drawn as the soon as the control is active
(or the previous feature is finalized).

See the demo on
<http://dev.openlayers.org/sandbox/elemoine/draw-feature/examples/snapping.html>.
You should have a point following the mouse as soon as the draw tool
is made active in the toolbar.

Cheers,
