Here's an early mnr dig from November on ClearVote - currently used in Seattle/King Co (same place Jeffrey Dean got his start- - where'd they go from there?)

Seems to be part of ClearBallot, but just did this one dig so far.

At the time, this company was pretty obscure but its name has come up several times since, i'm sure there's more material to be found on it now. The changes of these "Clear" companies being 'clean' seem slim.

ClearVote - What is it?
Short answer: one of the products of ClearBallot, the parent company.
ClearVote is part of the new "Clear - EVERYTHING" bundle:
ClearDesign = browser-based user interface
ClearAccess = ballot marking system
ClearCast = optical scan voting system
ClearCount = browser-based central count tabulation system
ClearAudit = automated audit solution

So if you a customer, looks like you can use it to collect all the votes and then self-audit what you did.
