C64/C128 CP/M Cartridge Interest?

There are many closet C128 CP/M users, and they'd never go for such a huge addition to their setup. A cartridge form factor, easy decision. Others would scoff at relegating their C128 as a dumb terminal to another machine (for instance, they could easily do the same thing by running a CP/M emu on their PC and connecting the C128 to the PC via a null modem cable). It's perception. * There is more to a C128 CP/M cartridge than just using the C128 as a dumb terminal. Some C128 CP/M apps might take advantage of the functions in the C128 itself, like the 40 column screen and such. Thus, memory mirroring and such would be useful. I didn't bring it up initially, because A) not sure if apps did that. B) I just wanted to start small, and thought that interfacing the Z80 to the CBM bus would be a good start * I theorized that a tiny CP/M board might be of use where N8VEM was too big or too expansive. * I so want to start learning Verilog. I thought, if I got a basic environment going, I could then take a look at virtualizing the pieces to an FPGA connected to the C128/C64. But, since I know little of Z80 and CP/M (having used it long ago), I thought going to FPGAs from nothing was too large a leap. * The next step after that is an accelerated CP/M. This plays in with my hope to obtain the rights to the SuperCPU for the C64/C128. It lacked accelerated Z80/CP/M compatibility, which I thought I could add, though maybe not. I'm gathering from the results that there might not be the interest I had theorized, which is fine. But, I thought I'd at least ask.
