You can use GNU screen to have more than one bash shell running, and you can use tabs and screen splits with Vim. I use to do this on my G2 phone; it's easier to play with Vim over ssh with a physical keyboard. Unfortunately, my phone lacks some critical characters like '|', '>' and '<', but it's really nice to be able to make edits wherever, whenever.
