Sounds interesting, it looks like a work that requires free time.

Thanks,

Right, I see what you're proposing: fractional voltage to encode multiple intermediate values between 0 and 1.  Nice!

Could I make a helpful suggestion?  It would probably be easier if you could write an internet draft to encode fractional ipv4 addresses.  So instead of having just 192.168.1.0 and 192.168.1.1, you could have a range of values in-between, e.g. 192.168.1.(1/2) or 192.168.1.(7/13). 
You'd need to work on the notation a bit because we're already using "/" 
to denote netmask, but I think the idea is sound, and it would solve a lot of problems with ipv4 deployment as well as providing a foundation for full ipv4 / ipv6 interoperability.  I.e. you'd solve two problems at once.

It would be a lot easier to handle this fractional idea at a higher level rather than trying to encode it at the electrical signaling level (see RFC 1925, Section 6).  The reason for this is that you'd probably need to make some changes at the electrical interface layer on IP routers to allow your signaling differentiation idea to work, and that could present some logistical problems.  Also, if you could make your proposal more generic by allowing floating point ipv4 addressing, that would probably be an advantage, but I don't think it would be necessary to go this far.  Fractional would be more than enough.
