As a sign that I'm trying to ramp up development (especially getting a MOSS 2007 layer working), I've snagged me a spot on the codeplex for this code. Feel free to ask for features, provide ideas, critique whatever on the forums provided. I'm also working on an ArchivePSProvider which will allow navigation of Zip and Tar files as hierarchical stores as well as providing some pipe-friendly cmdlets for tar/gzip/zip, e.g.  get-childitems -inc *.log | out-tar | out-gzip
