Use emacs shell (eshell) in multi-term -

i set multi-term in emacs24, i'm trying configure able open multi-term running eshell.

how can it, specify eshell shell program ??

i'm trying instance create equivalent eshell:

(defun multi-term-bash ()                     "make multi-term buffer running bash."                     (interactive)                     (let ((multi-term-program "/bin/bash"))                       (multi-term))) 

i'm afraid answer here is: can't. =/
multi-term needs native shell run. meanwhile eshell isn't shell, it's interactive emacs mode (written entirely in elisp) acts shell.

there other ways achieve overall objective, shell-switcher , multi-eshell first come up.
