LAMPS: Is it ok to run SMB on a Web Server?

[lightnb]

I have two computers:
A) a Kubuntu Desktop machine that I do all of my work on
B) a Ubuntu Server that runs a LAMP stack and nothing else.

The server will be publicly accessible on the internet. Since the server is on the same LAN and is literally 15 feet away from my desktop machine, it seems absurd to FTP the files across the internet to get to a computer on the other side of the room.

I was thinking that it would make sense to share the web root of the server using SMB and then mount the share on my desktop computer, so that I could edit the files directly.

Is it a stupid idea to do this? Ie, Does that open up security vulnerabilities?

Are there better alternatives?

Thank you for your advise.
