Break down large or regular updates into small files and use differential instead of bulk download or imports in SMP products
Currently the design of Symantec Management Platform requires the end user to download a large file (getting larger almost every two weeks). This is true of the symantec.pl.xml  file as well as the PMImport files for Patch Management Solution.
Wouldn't it be better and more efficient if the files downloaded were broken down into very small chunks (for patch we could have a file per Microsoft Bulletin)?
In addition using differential mechanism such as what's in use in source version control (I'm thinking about Git here, in use for the Linux kernel as well as many Gnome or open source projects). This could ensure only the changed files are downloaded which in SQL intensive process such as the PMImport is reduced to what is required only and no more.
