We run 5 light jets and use Airiops, it takes a bit of getting used to. we spent 2 years trying to find something better, but failed. It runs on your local server, and has the ability to "dump" data to an external FTP that a bespoke front end (web based) can pick up. We haven't yet developed a crew portal, but have used the data transfer to link to post any empty sectors on our website - the technology is there, but you will need to tweak it to your own needs. It does not deal with plans / plogs and Wx / notams at all, but does distribute information well to handling agents, crew etc.
