complicated is relative, this is a complicated world. I am not sure that this is a disadvantage, you could just as well say bitcoin won't take off because it is complicated.
-it is far removed from simple mutual credit which many of them don't really understand.
The plan would be to make the frontend as simple as possible, and follow as many Mutual Credit precedents as possible
-these groups prefer to operate in plain sight, than to use encryption
I agree, which is why identification of users is an important factor. Encryption of the block chain etc. is part of bitcoin security and doesn't have anything to do with whether transactions are transparent or not.
-they have no resources for accounting systems
Indeed. This could be a problem, but my thoughts are that these systems will be build for bitcoin in due course.
I am still undecided whether there really is a point in trying to do this. There are other systems, that may well work (I have still yet to review them). My main motivation is to leverage the popularity of bitcoin to drive adoption of a Complementary Currency, my secondary is that bitcoin is going to have a huge amount of technical and other solutions to make digital currency more usable (e.g coincards, POS machines etc.)
I will have a look at your site when I get a chance. Thanks for your input.
