"there are problems transmitting separated Data and Clocks via single cable, especially in the case master clock is included."
What exactly are the problems? Seems to work perfectly and sounds significatnly better than any S/PDIF I have heard.
"The only "problem" with S/PDIF is the master clock recovery which is done from the Bitclock by multiplying it and PLL-ing it. This of course results in high jitter in the master clock. But since 44.1 (or multiples) sampling is of primary use with your application,"
Actually, it's not. I only use 24/96 and I'm doing systems with the Northstar transport that are 24/192. Both of these sound superior to 44.1.
"you can easily use one of the latest Crystal or AKM S/PDIF receivers and configure it in Master Mode with own master clock generator. In this case the master clock is on-board with the DIR and DAC and if precision external XO or TCXO is used you can have as low as 5-10pS (RMS) jitter. This will be free of the problems with the I2S cable."
This is still using a PLL to derive the clock. Seems like it will have more jitter than the simpler I2S interface.
