According to AllThingsDigital’s Kara Swisher, Facebook is considering raising additional funds for expansion or potential further acquisitions. Facebook’s first and only acquisition thus far is Parakey, a company created by two of Mozilla Firefox’s core programmers.

Considering the costs of maintaining Facebook between staffing, facilities, and server costs, I am not surprised that Facebook would be looking for more money. If I remember correctly, Facebook has roughly 40 million+ members, is expecting to make around $150 million this year in revenues (compared to $50 million in 2006), and is expecting to file for a possible IPO in the future. If Facebook decides to pursue an IPO, it would be around 2009 or beyond.
