No, there's no way to snap to a handle, unless the handle just happens to be at a point which could otherwise be snapped to.

Ok, Here are some videos to demonstrate all the snapping that I've added for handles.  Please note, I'm not talking about snapping to grid, I am talking about snapping to useful construction angles relative to the opposite curve point and handle.
 
So, the following snaps are shown:
 
1) Snapping to smooth a cusped node - SnapToSmooth.mov
2) Snapping to inline, and 90 degrees to inline - SnapToInlineAndNormal.mov
3) Snapping to reflected angle - SnapToReflected.mov
4) Snapping to parallel direction - SnapToParallel.mov
5) Snapping to 90 degrees of parallel - SnapToParallelNormal.mov
6) Snap to logical triangle (useful for square corners?) - SnapToTriangle.mov
 
The useful thing about these snaps is that they will enable you to perform common curve construction, completely independent of grid or set axis.  You can use them in tandem with a second action while holding Shift to snap the handle lengths to match the preceding or following handle (while maintaining the direction you already snapped).

@owenr and @m4nticore Thanks for this! It does seem to only be those two options which are drawing strangely (2:1 Triangular and Horizontal Triangular) which is very odd... I'm looking at fixing it right now... Also, the disagreement between isometric grid drawing and snapping is a side-effect of another change I had to make the other day - I've reverted it so that the code acts as expected while I search for a better fix. I'll also sort out the colour drawing - I'm surprised as I've seen this working, but obviously something is not quite right... Sorry again, but it'll be sorted pronto!  

When using a grid different from the standard one (ie. isometric) the snapping is offsetted from the real snapping point.
