Ajax arquitecture

Ajax arquitecture

I'd like some expert advice about an arquitectural testing I'm trying right now with a web using jquery and jquery.history:

The idea would be use a <div id="content"> as a wrapper for the main content of the web and try to load everything via "ahah", ajax returning html that replaces #content, so the menu loads new content to put in the wrapper, but... this new content possibly could have new jquery... example:

clicking in a link of menu would load the following php including as is in the wrapper:
<script>
xxx
</script>
html....

Navegability would come with history plugin that allows us to attach states of the webapp to a certain url

Would this be a good starting? I have a small prototype if anyone is interested
