dm6446 video application development

Hi,
   I am trying to port a video application which was developed with CCS 3.1 on a EVM DM642 board to a camera with a DM6446 board. The DM642 based application used CSL for getting access to the video. Right now I have CCS 4.1 and from what I understand CSL is not available for DM6446. So I am trying to use the DVSDK and Codec Engine framework which requires development on linux.

Target hardware : DM6446 based camera (not an EVM board) - video out, ethernet, jtag, NO serial port.
Tools Used : Windows XP : CCS 4.1 and XDS560 emulator
                     Linux : downloaded DVSDK 2.00 (and the DSP/BIOS and CodeGen  tools) linux from TI's site
Need to do : Capture images from the camera, process them, display it out to video port and maybe stream them over the network


The questions I had are
1) The DM6446 based camera does not have a serial port and setting up the shared file system requires that we use to the serial port for this setup. Is there an alternative?
2) More generally, is this a viable hardware/software setup? I have used CCS before but I am not familiar with the linux toolchain nor I have used  the DVSDK/Codec Engine framework before. Do I need any other tools, software or hardware packages?
3) Is there a video loopback example for use with CCS 4.1 on windows xp and DM6446? I could not find anything in the downloads section. At this point a bare metal application running just on the DSP (ARM not used) should also do.


Thanks
