TheDeal.com reports (registration required) on two funds, managed by GE/CS and Morgan Stanley, dedicated to infrastructure investments. They raised $5.6bn and $4.0bn respectively. Obviously, 'long-term stable cashflows' is what people are looking for.
Judging from the report, they focus on traditional infrastructure assets (airports, ports, waste management, parking), but the Morgan Stanley fund also mentions 'communications'. That's great for FTTH aficionados.
