Multiple forms on page, submit with ajax?

I'm trying to build a module wich allows for a page and all it's translations to show right next to eachother on a form for easy translating(instead of going page by page).

However, I was thinking, what of instead of building my own forms, I just load the node edit/save forms next to eachother. This would require less code, however each form would have it's own submit function, wich takes you off the page and brings you back to wherever you came from.(Kind of like the Easy translator module, only with pages-translations being seperate nodes in this case.)

Is it possible to execute the submit function through an ajax request? How much trouble will I be in since the form for each node uses the same kind of id's and such?

Thoughts on this?
