CS3 and CS3 update packaging

I'm doing the package creation part of InstaDMG now. Wanted to get people’s thoughts on Creative Suite and Creative Suite *updates* deployment, specifically. Via the logGen, pkgGen, Package Maker route I’ve made packages for CS3 Design Premium (minus Flash and Dreamweaver b/c we don’t do much interactive media) & all updates current to, well, today. The update package brings cause for concern. It’s huge, logGen found files to remove, and I wonder how realistic it is to expect to update it frequently. Have people played with packaging this app and the updates at all? In general, for file removal, I’m thinking a preinstall script in the package will work. What do people think?
