Archiving Social Media & Integrating It With Email, SharePoint, File Shares, etc.

We have advised clients to implement social media archiving, but we have not done the engineering/implementation yet. Regardless, I wonder when the large archiving software solution providers (Symantec, EMC) will acquire, build and integrate social media archiving solutions with their product. I see this as a separate module versus a completely integrated system, but I unified system just the same.
