Doesn't that depend on my ISP running basically an open relay, if I'm trying to mail from [email protected] and they only provide [email protected]? Always figured they'd just dump the request with a "i don't know you".

No because relays can be closed, and usually are. Your ISP's SMTP server requires authentication, using the credentials they gave you, and almost certainly uses TLS also.
Your [email protected] address (or perhaps the me part of it) is used for authenticating, along with the password. It will likely be used as your envelope address when sending; the SMTP command will be MAIL from: [email protected], though there could be flexibility there to accept other sending envelope identities.
In any case, your mail's From: header will have the [email protected].
If the ISP were to filter on the From: addresses after receiving the content of the e-mail, you'd have to negotiate something with them.

Ah yes, doh.
