Another vga device question

I am also looking for something not quite like this, but along the same lines. 
We have a Windows application and would like a bare-bones cheap interface to a 
display via Ethernet.  It would be Ethernet in, VGA (or even RCA) out, the only 
intelligence necessary would be to recognize a jpeg file coming in and render it 
to the output.

We have located at least one "media player" type device that might be coerced do 
what we want, but it is targeted to the entertainment market and would be 
massive overkill for what we want to do.  We don't actually need an onboard file 
system, for example - the images would be stored on the PC.  Nor do we care 
about video or audio.

Thanks,

Just to muddle up this thread a bit more, I am planning a DSP box based
on a TMS320 series ISA board (which I happen to have in quantity) which
runs under Win3.1.  The target will be a PC-104 board with this one
peripheral and a ROM-DOS and flash file system.  I would actually
prefer to strip the display controller from the CPU board (or find
a 386/486 SBC with only RAM, ROM and a COM port.  The DSP board
runs an RTOS which is managed by an app on the Win3.1 host.  I
would appreciate pointers to any "mini" Windows 3.1 development
resources -- an example of a mini Win 3.1 application is MS's
'scsi interrogator' which resides on a 1.44 MB floppy and boots
to a customized Windows interface.  I can't use WinPE or BartPE;
the DSP's manager needs canonical Win16.

Replies appreciated.

The ProASIC/Arm chip should be more than enough to receive ethernet,
decode jpg and drive VGA.

OK, Ulf, AT91CAPXXX works too.

I like the AT91 just fine - but we are looking to buy, not build . . .

Maybe I just don't know the right name for what I am talking about, because it 
has to be out there.  We have looked at a "media player", which can drive a TV 
with video, audio, still pictures, etc. under control  of  a PC "entertainment 
center" type program.  The device has the right I/O configuration - Ethernet in, 
RCA plug out (thogh I think we would prefer a standard PC video monitor 
connector out).  Hobbyists seem to like it, it looks like it might be possible 
to send a .jpg through it, it's under $100 - but it is way overkill for what we 
are trying to do.  For one thing I would just as soon not interact with some 
onboard file system - send a .jpg over Ethernet with some appropriate headers 
and have it displayed is all we need.

What we are after, really, is just a cheap remote display that has an Ethernet 
port (wired and/or wireless) and would know what to do with a .jpg that arrives 
over it.  Are there such things?  If so, no intermediate box would be needed.

How many?  For the right price, someone will build it for you.

ProASIC can be done for less than $50, qty 1K
AT91CAP can be done for less than $30, qty 10K
