[Seaside] magma as a multimedia database backend for seaside application

[Martin Schubert]

hello out there,
i a struggling with using the magma-seaside extension as a multimedia 
database backend for my seaside application.
i don`t want the files to be located on the os filesystem. as anybody 
can imagine: when i am loading a list of entries (whereas each entry has 
a mimeDocument instance) into the WAMagmaSession the image size explodes 
as more and more sessions are used.
there is especially one problem i am facing :
    i need a possibillity that the mimeDocument instance of each listed 
entry is only loaded into the local cache (or WAMagmaSession) when there 
is an explicit request in doing so. when an anchor is clicked or 
something like that.
any suggestions or experience on a topic like that?
