Roll-ups in the content delivery space

Two announcements came into my Inbox this morning that appear related:

• Abacast is acquiring Tukati Inc., formally merging the companies that had a partnership the last couple of years.
• Highwinds Network Group has partnered with Octoshape to create a Hybrid Peer-to-Peer Content Delivery Network (Hybrid P2P CDN) solution for streaming live events to millions of concurrent worldwide viewers.
