Not without a _lot_ of work. As far as I can tell, there aren't any compilers or even header files on the device, so you can't build any C/C++-based packages on it as is. You would first have to install compilers and a development environment, which would be a fair bit of work. It's much easier to build packages using one of the unofficial SDK's on a PC and then copy them over to the device.

As far as installing goes, you can already install things on the public internal SD card partition (/mnt/ext1) and on the external SD card (/mnt/ext2), and the device is set up reasonably well to look in those areas for software and configuration files (thanks PB ). There are some partitions that are mounted read-only, and those could be remounted with write privileges with root access. However, as the original poster says, changing the contents of those partitions could result in their being unusable (if some sort of checksum lockout is being used). So, it will take someone who is not afraid of bricking their device to play around with that.

Having root access will allow one to look at files that are currently unreadable by the reader login account, run daemons (services) that require root privileges, play with the networking... So I think it will be more useful for opening up existing capabilities of the device as opposed to adding software to it (which you could do pretty well before).
