sharing documents from within word directly options?

Can someone explain me what is the difference between sharing a document in Word using a Skydrive and SharePoint and what security issues should I considered before sharing document directly from within Word?

I know that skydrive is cloud application and you can store the documents and access them no matter where are you, but what is the advantage over sending document as email attachment ?

thank you
