Document Sharing and eMailing

Document Sharing and eMailing

So let me see if I have this right:

1. If I upload a document into the Documents area of the CRM, I can't share it, but I can email it. 

2. If I upload a document into Zoho Docs, I can share it, but I can't email it. 

How can I both share a document and make it available for me to email from the CRM? I can do this in Google.
