Office SharePoint Server 2007 TechNet content released as .chm file

I just noticed that the SharePoint IT pro documentation team has released Office SharePoint Server 2007 TechNet content as a downloadable file, to be able to access the content also off-line (intercontinental flights etc.). According the announcement, the package will be updated in monthly. This is also good reference guidance, if you are in customer premises and want to verify something without access to the actual site.
