ailef,
We do possibly have plans on adding other OS's; however, there is a very limited amount that you will be able to do with them. VBP is not a self contained boot manager, it would more or less just be adding/deleting other OS entries. We may have the ability to move them around in the list but there is a very limited amount os features that would be added to these Other OS's.
I hope this somewhat answers your question. It has been on the table and is still being kicked around.
Thanks for your inquiry and if you have any ideas/features that might be useful to add to VBP or any other future PROnetworks program please let us know.
Thanks,
Jason
