// I haven't used PQ either. In fact, has anyone used PQ in the // last couple years?
Yes. In the past few years I've worked with teams building two unrelated applications with it. One went through a technology trial with a Tier 1 US telecom provider, but then floundered for unrelated reasons. The other was, for years, responsible for moving several millions of dollars around every month between a few hundred global GSM operators. The company has since been sold; the buying company initially decided on using our platform to replace theirs, but then everyone I knew there left, so I can't comment on current state. The web site for the service is at least unchanged. Sadly, both those projects relied on an update mechanism which was a proprietary extention not included in the distribution. Getting a good update mechanism that fits well with the distrubuted version has been an ongoing challenge. The official directory folks at ALU were, at least until shortly after the merger, using it as a front end for an assortment of proprietary HR-type systems. I believe that was dying out, although I can't say as the folks I knew there have since gone over to at&t. That group's version was an evolutionary cousin of the Plan 9 one. I'm also using it on a personal project, and am working on updating the distrubution, in part in response to second-hand requests from some folks who want to update an application using (almost exactly) the Plan 9 version on Solaris. So, yes. It's probably a single-digit number of active projects and double-digit user base (not counting users of the services these applications provide, in which case it's at least single- digit thousands), but non-zero.
