I don't believe flZogu2d has done anything on the lines you are thinking with the link you mentioned in your previous post. Of course, I can't speak for him/her.
PortableApps has repackaged the Java Runtime Environment in a portable format so applications that are flexible enough to find it in other locations than where it usually resides can find it and function. No one has repackaged PersonalBrain and Java Runtime Environment together in a PortableApps format that I know of. There are legal copyright reasons for that if I am not mistaken.
I authored this post http://forums.thebrain.com/post?id=5042085 that you commented on the same lines as this one here. I believe I know what you wish to have happen but I think a modification of that situation can happen. Instead of having PersonalBrain and Java Runtime Environment combined together in a PortableApps package, if the developers review my post that I mentioned above and give their blessings (and possible instructions to the uninitiated) then users of PersonalBrain can truly have a portable experience with the application using the PortableApps version of Java Runtime Environment.
The developers can also deploy Java Runtime Environment within the portable version of PersonalBrain if they desired without using the PortableApps version of Java Runtime Environment.
At this point the key points of the thread I started above is making PersonalBrain even more portable than it currently is with the inclusion of a Java Runtime Environment that is not "installed" on the computer of the user, bringing in all extra files and folders that are created after PersonalBrain is launched back into its own folder structure, utilize relative file/folder paths instead of absolute file/folder paths, and ensure data integrity is still upheld to the highest level possible.
Haven't heard back from any moderator or developer about these key points but I am still hopeful. I hope this information is useful to you.
Thank you for your time and attention.
