Because you never know where new knowledge may appear. Effective tools should be maintained as long as they are useful.
Specifically, it was data from the supposedly now 'retired' Pioneers 10 and 11 that alerted scientists a couple years ago that there may be some problems with our current understanding of gravity.
After tracking the faint signals from the probes, scientists were able to determine that neither probe had traveled as far as it should have by a substantial margin, and they have now been able to eliminate most proposed explanations for this sun-ward acceleration, including nearby large undetected masses (Pioneers 10 and 11 are headed out of the solar system in nearly opposite directions), unaccounted effects in the the propulsion systems, space debris, solar wind, etc etc. Recently, this same anomalous acceleration was measured for the Galileo and Ulysses probes. The ESA is designing a series of missions to look into this anomaly and others related to gravity.

Well, that comment about Samba needs to be clarified. Many Mac users use Thursby's DAVE app, which is a CIFS client/server, so Samba shares *could* be an issue.
Also, by-the-by, AppleShare passwords are two way encrypted by default now (as of system 8.x, I believe, but certainly in 8.5 and later).
