Would be nice if we could get the installed packages for a given project, just like Install-Package.
Among other things, this would enable a simple scripted way of updating all packages in an entire solution:
foreach ($project in Get-ProjectNames)
foreach ($package in (Get-Package -Project $project))
Update-Package $package.Id -Project $project
