More around the automation side of things, to start with: -
A powershell aware installer.
A way to determine installed features, other than "Setup.exe /Action=RunDiscovery", a powershell cmdlet that returns a recordset maybe.
Both of these would help enterprise management.
Replication
Allow replication from one distribution database to another and then have multiple subscribes hanging off the second distribution database. Effectively this would mirror the possibilities within Sybase RepServer and their use of RSIs. The major benefit to this comes when replicating to multiple subscribers across a WAN. By sending the data across the wan once to what is effectively a staging DB, there is less traffic on the WAN.
