Kirk:
We may be onto something here:
Joomla Multisites Component For Joomla 1.0.x
"...two multisites components developed in parallel. Both components makes it possible to run multiple sites using the same Joomla 1.0.x installation. The "Original Version" patches a few Joomla source files and aims to provide multisite capabilities within subdirectories of your existing site. Distinguishes content and entities between sites by assigning them different database prefixes, easily administrated through the backend. The "Alternative Version" enhances OpenSEF's (recently renamed to NuSEF) multisite feature..."
I am familiar with openSEF and will look into their multisite feature as well. Didn't know it even had such a thing since SEF stands for Search Engine Friendly. Go figure.
Will post here or Skype.
