That's absolutely no problem. The easiest way to do this is to use sshfs.

Well at least it would be possible. Doing it for the first time it would require some effort (mounting the remote bin and lib directories, maybe redefine the $PATH variable) but it's a common technique in every centralized unixoid network system.
However I think the easier and more robust idea in this case would actually be to duplicate the software which, at least between ED and the Raspberry, would be very easy since they have the same architecture. So either way would be fine.

I'm not sure if we can run Maemo software under a Debian installation on the Raspberry. If there is a way it should also work under ED in some sort of "reverse debbie" because the principles we need would be the same. So if anybody has an idea of how to do that we can start testing right away.

Yet, it would require already running N900 (here we went back into my question about 2 OS mounting the same partition, simultaneously). Thus, we would be able to share both WiFi and Cellular connections, at the same time sharing partitions, without additional overhead (Raspberry Pi read things from N900's partition via USB, and at the same time, N900 share network via USB networking).
If we connect the N900 to the Raspberry in PC suite mode so that we can access the N900's WLAN and cellular interfaces we also have a network connection betwen the N900 and the Raspberry which allows us to mount the N900's filesystems on the Raspberry via sshfs.

Yes they do but it doesn't matter since we simply replace the mass storage connection with a network connection.

If we'd actually do that via loop devices with write permissions on both sides that might be a problem. Be we don't use loop devices, we use network shares just like you might know them from Windows networks.
