I would agree that the IVOA "has" conesearch, but SkyNode has not been so widely implemented - partly perhaps because it got too tangled up with a particular service implementation?
My own view is that on the simplicity/complexity axis, our initial version of TAP should be closer to conesearch than to SkyNode - i.e. maximally clean and simple. That way, we have more chance of getting compliant services and clients widely implemented.
