M+x ansi-term should do it. I'm not sure how well that scales to many terminals though. M+x term also works. There is also eshell.

ansi-term and term are massively buggy.

I've never been able to get it to deal well with vast amounts of output well. Constant overwriting issues etc. Definitely prefer to use tmux + emacs considering the huge amount of stuff i end up throwing at my term.
