That's a good point Ken. I participated in a focus group during CDUGNA this year and recommended that they continue to offer the .mdb-based repository for developers that choose not to implement CE.
The Business Objects staff was surprised that this was an issue. I likened it to installing CE. You can house the System Database in Sql Server, Oracle, etc..., but CE will attempt to install the MSDE by default. My recommendation for CR products was that it install the local repository by default, but allow you to migrate to CE if desired (for integrated security and Business Views support, for example).
Hopefully, somebody listened...
