In no particular order:

1. a client configuration wizard and dashboard

   • (to create multiple flavors of your current build, to design your next builds, to see what configurations are in situ)

2. a client inventory system

   • (discover and list instances of Skype on your network)

3. network monitoring

   • (see and measure Skype traffic, analyze sources/destinations, detect non-compliant nodes)

4. a client compliance plug-in

   • (to capture Skype call records, to record conversations, and upload them to...)

5. a compliance archive server

   • (to store call records and call recordings in a searchable manner, to destroy those records per corporate policy, to provide controlled access to the records)

6. a rogue client blocking tool

   • (so you can block streams/packets by a given Skype client)

7. malware inspection client for file transfers

   • (so you don't send or receive viruses)

8. proxy service inside the firewall

   • (so you have a chokepoint)

9. superdupernodeplex box in the dmz

   • (running 100 instances of Skype available to become supernodes)

10. Skype account creation/deletion/changes and deployment

    • (triggered by personnel actions)

11. Skype account funding controls

    • (to top up SkypeOut credits, report on costs/activity by corporate cost center)

12. Skype account supervision controls

    • (so some supervisors can see some all of a subordinate's activity)

13. client configuration updater

    • (so you can change policies)

14. client software updater

    • (automatically get the latest from Skype but deploy on demand per the client configuration system)

15. Skype extras filtering

    • (to allow or prohibit some or all Skype plug-ins)

16. contact list LDAP sync

    • (to populate Skype contact lists from the corporate directory)

17. customized in-Skype alerts

    • (like in-house warnings/error messages)

18. custom browser tabs

    • (intranet home page, Skype tech support)

19. enterprise Skypecasts

    • (hosted securely and privately for team meetings and client presentations)

20. enterprise bots

    • (able to inject disclaimers into chat or calls or fetch useful information)

21. Skype enterprise heartbeat

    • (so you can see the current health of the parts you control and the parts you don't)

bonus points!

22. deep integration with Salesforce.com, sap, etc.

    • (triggering useful conversations)

23. datamining tools that run against the compliance archive

    • (to learn from your hive mind)

24. project podcasting/vlogging tools

    • (to improve institutional memory and project communication)

25. private extras gallery

    • (the better to distribute sanctioned home-grown or locally adopted tools)

26. deep integration with attention/routing manager

    • (so your most valuable customers always get through)

Is this feature overload? The kind that kills consumer products? You can design around that problem if the enterprise market is strategic.

Off-topic 1: Corporate in loco parentis behavior always bothers me. Children grow up and seize control of their lives from their parents. Locked-down systems assume employees never grow up.
