[Taler] Mutual credit on GNU Taler

[Billy Utermann]

Hi there,
I've been following the development of GNU Taler these last years and I really 
like what you all are doing!

I'm researching protocols for creating and administrating mutual credit 
networks and I wanted to ask if somebody here has any plans on trying that with 
GNU Taler.
Taler seems to be working mostly with existing banks, which a mutual credit 
network does not have. Is it possible and wishful to use it without a bank?

For my recently submitted bachelor's thesis, I researched the Credit Commons 
protocol, which "supports independent entities to keep track of their exchange 
on a ledger which they control. Ledgers can be recursively nested, allowing 
trading blocs of all scales to exchange with each other without using money." 
(creditcommons.net)
The current reference implementation is somewhat lacking in terms of privacy 
and security primitives, so that's why I landed here :)

I'm thinking mutual credit (meaning the system must track negative and positive 
limits per user) is contrary to a value-based / token-based system, but maybe 
I'm wrong and they can be combined. 

Let me know if this list is the wrong place to ask, or if there is information 
that I missed somewhere else.

Thanks in advance,

Billy
