Connect to iWeb site without domain.sites2

I've gotten myself in a bind. I'm traveling, and although I brought along the entire folder for an iWeb site (that is, all the material that iWeb created) I failed to go into my Library and grab the domain.sites2 file before I left.

So here I am, a couple of thousand miles from home, no way to get at the Mac that has the correct domain.sites2 file, and needing to make a small change to the website.

Does anybody know how I can point iWeb to the iWeb-created site that's sitting on my laptop? Is there a way to edit domain.sites2 to point to where the material is?

I'm away for 2 weeks and I'm hoping not to have to wait until I get back to update the site. It's not a complicated site and I suppose I could use the sources to recreate it as a new site, but I'm supposed to be working on something else here and I'd rather not take the time.
