So you'd submit to a hidden <iframe> and then disable the main page?

In past projects of this nature I used to create a new <iframe> each time 
I submitted something, so there'd be no problem submitting multiple times, 
it would just update the UI multiple times (and if they shouldn't, then I 
would prevent the submission by disabling the entry points to submitting).

More recently I just spawn a new XMLHttpRequest for each submission.

Wouldn't object references by lighter weight?
