Maybe, someone can use the following information.
Just now, i run more or less for fun a cost estimation for OpenAcs and Dotlrn using sloccount. This software estimates the cost of a system based on the lines of code and various heuristics of the COCOMO model. Currently, it misinterprets a few files , but overall the input numbers look plausible. According to this estimate, the development effort of oacs+dotlrn is worth 18mio US$.

Total Physical Source Lines of Code (SLOC) = 487,182
Development Effort Estimate, Person-Years (Person-Months) = 132.77 (1,593.26)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 3.43 (41.19)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 38.68
Total Estimated Cost to Develop = $ 17,935,662
(average salary = $56,286/year, overhead = 2.40).
