Ok, I understand now. I had my fear amount of problems with this.

Yes, I know. If I remember correctly, Seth once asked for some of the 
configurations, that they could start with ":guest 
databases:mydatabases". I think you can use this with user.databases 
but I'm not sure.

Its probably too late for that, but a lot of these path could have 
been as a relative string representations (as the example above).

And I wonder if the kernel could have implemented this directly. 
Something that goes like this at system.paths:

path15 = @frontierpathfolder

which in the kernel translate  the filepath to an address that 
represent the folder in which is Frontier/Radio:

@["HD:Users:emmanuel:Radio UserLand:]

So addresses could resolve for example to the following if they are 
in this path:

@[":Tools:myPictures.root"].myPicturesData.prefs

See the leading colon that tell Radio/Frontier that the path is 
relative to path15.

Hope this make sense.

Cheers
