OT android question

[Derek Trotter]

I have an android tablet and have link2sd installed on it so there's 
room to install what I want on it. This works fine, however I have to 
have the ext3 partition with the same data on multiple sd cards I use in 
the tablet.  I once heard about an app that creates an image file on the 
part of the internal sd card the user has access to and mounts that 
image file instead of a partition on the external card.

Does anyone know of an app that will do this?  I have looked for weeks 
and not found it again.  Also how would I go about creating the image 
file myself and configuring the tablet to use it?

I would like to be able to change sd cards without having to shut down 
the tablet or having to repartition them.

Thanks to anyone who can help.

Derek
