Q:

how can I export a vector shadow in illustrator to place into photoshop as a smart object?

I know you can export the asset as a PSD and open it in Photoshop. Is there a more seamless way?
Update:  I'm an idiot.  Someone else created the logo, and the shadow was it's own layer on multiply and not a normal drop shadow effect.  

A:

Yeah. Just copy сmd+C in illustrator and paste in photoshop. Pasted object in photoshop will be smart object. This smart object will be editable - after double click on it in layers palette in photoshop it wiil be opened with illustrator. 
Mini tut.
