GrIDsure have already been chatting with the RNIB and have had a positive response about the suitability of the system for the sight-impaired, see this response to the original GrIDsure article on the Reg:
The mobile application could be made to read out the numbers on the grid quite easily on most modern phones, which would still be protected from a "shoulder listener" by the GrIDsure system, in the same way as a "shoulder surfer" is defeated. (although that hasn't been built into the existing system)

re: will it help fix this
I think you were referring to http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-26-102934-1
This is a specific issue for certain SUN JRE's for PC's, and does not affect J2ME.
You are right that any mono-culture is vulnerable to one exploit sweeping through it, but MIDP/J2ME virtual machines on mobile phones are not a mono-culture as they are made by different vendors, running on different OS's and Processors (contrary to popular belief all JRE's are not made by SUN).
Windows is a far worse situation, found in very similar guises on only two major CPU families with similar op codes (the binary codes required to make things happen on the processor when a virus has overflowed data into instruction space).
I have posted more detail about mobile security, with an invitation for people to ask more questions on blog.masabi.com if you have other concerns.
p.s. I think C-Commerce was a typo, we've never heard of it either, and wondered if it was a US translation to "Cellular-Commerce" or something....
