Importing a proprietary user database into BuddyPress like a boss

Disclaimer: this may have changed in more recent versions of BuddyPress, so your mileage may very substantially. Please let me know if something's not working, but caveat lector none of this comes with any warranty or support whatsoever.

A bit over a year ago, I asked a question on the WordPress Stack Exchange site about importing content from a proprietary database into BuddyPress, the "social network in a box" plugin for WordPress. Not getting anything resembling a response, I ended up writing a whole schwack of MySQL statements. After answering my question on SO, I've averaged about an email every 4-6 months about how I managed to do what I did. Alas, I was a total jerk and couldn't find the SQL I use and ended up ignoring most of them.

Until today!

Note that the following is not a one-click script that will import your users. It's a starting point I'm posting in hopes that somebody finds it useful. You will need to modify it for your purposes, and please, please, PLEASE don't use this on a production database, and make backups frequently. I take no responsibility if you screw something up with it!

Also attached to this post is an importer script Michael Dimunation sent me awhile back after I emailed him the SQL query in question. I have no idea what it does and have never used it -- again, same caveats apply, but hopefully somebody finds it useful.
