Import Export - JSmigrate - newer version and its developer?

Hello, just out of curiosity...
does someone have a newer copy of the JSmigrate component?
Newer than v1.1.2 from JoomlaCode repository. As far as I know, there was a custom made and extended version, but it has never been published.

"Rich is made fantastic changes and added support for XML files. So we are impatient when he submit those changes and make new version build."

Your comment on JoomlaCode mentioned a user called "Rich Roth". Do you have contact infos? Did you ever have access to the customized build?
