No, it won't.

CU-SEEME requires that the driver support the 8-bit palletized format, and,
furthermore, that the palette be loadable.

I happen to have written the driver for an unfortunate card that uses a
fixed 8-bit palette that is not loadable, and so cannot support CU-SEEME.
Well, it *could*, with some work on the driver, but I suspect it'd be pretty
ugly - the driver would have to do a "nearest color" match.

With 16 or 24 bit RGB, the driver could easily implement the LUT to provide
an 8-bit palletized format. But the driver MUST support this format. So,
based on the above statement:

"This driver will support 16 and 24 bit RGB"

that driver will not support CU-SEEME. Those formats do CU-SEEME no good.
