There are at least two parties working on it who have interest in certain features to be working: It's the NuGet shell within MonoDevelop, so custom PowerShell hosts need to work as well as a bunch of things needed by NuGet. Then one of the more prolific developers actually gets paid to work on Pash to support features related to PowerShell add-ins and a few others. (My own efforts so far were mostly bits and pieces, missing cmdlets (there are still a lot of those), test cases, and weird parser behaviour, mostly due to my history of golfing in PowerShell – golfed code makes for some fun tests of edge cases.)
