There have been a number of posts lately about closing the ssh/scp gap, and with great reason. It's stupid annoying to find a file on a remote machine that you want locally (or vice versa) and have to open a new shell and start mucking around with paths.
Instead of all these hacks, it would be awesome to see support for in-session file transfer built into ssh/sshd.
This doesn't require any external tools, you just have to set up the config files. I think this is about as close to 'built in' support as you are going to get.
