There are several emerging (e.g., ESME, Laconica (open source), OraTweet (Oracle), SocialCast, Present.ly, and Yammer, etc.) but so far, none address to my satisfaction the issues posed below (which I happened to post on the Present.ly support forum).
Directory, Archive/Audit, Security/Compliance / Enterprise / Discussion Area - Present.ly Support
Most IT organizations will treat "Twitter-like" tools as they do Enterprise IM products which will raise questions such as:
- Directory integration
- Policy management (including policies assigned to people in certain roles or groups)
- Archive (for audit, compliane, records management, etc)
- Security (access controls, etc)
- Integration with anti-virus and content filtering tools
- Integration with Microsoft Communicator and IBM Sametime
- Application development (plug-ins, integration with productivity tools)
I know there's a lot here but these tools are going to be asked such questions by many IT groups, hosted or on-premise.
I would add one more: 8. enterprise-class administration tools to support some of the above requirements.
The biggest adoption barrier for these types of tools will be similar to what organizations have to do with any communication method re: security, records management (e.g., e-discovery), compliance and other burdens placed on enterprise IM.
(Added after posting): One thing I forgot to mention - there will be a race of sorts between IM vendors/products and these social messaging tools. For instance, can Microsoft exploit its acquisition of Parlano and deliver it as a Twitter-like service within OCS and can IBM expand Sametime to emulate the application behaviors of Twitter-like tools. The rationalization will be along the lines of "workers already spend time in their IM client so why give them another communication tool and cause them to switch back-and-forth" or "let leverage the the infrastruction deployed which already handles the archival needs", etc etc...
BTW - no response yet from the vendor.
