I don't know if they have an alternative currency but there are some community banks similar to that one operating there (http://www.bankomunales.com/ (in Spanish)).
Cool, thanks for the link. For anyone else interested...
"Fundefir created a model of self-managed financing called Bankomunales con K, based on the exclusive use of funds from members of community groups, as a source of financing."
"Currently, there are around 150 groups, or Bankomunales, in 9 Venezuelan states."
