Template:Unreferenced Template:Infobox Software Acquisition is a Gnutella-based peer-to-peer and BitTorrent client for Mac OS X. It is based on LimeWire and is a shareware product, priced from $24. Acquisition is noted for being one of the most polished peer-to-peer applications available for Mac OS X, making full use of Apple's Cocoa APIs.
Acquisition's use of the GPLed LimeWire core libraries has caused some controversy. Critics argue that the two parts of Acquisition (the GUI and the modified LimeWire core) are not really independent and thereby constitute a single work which cannot be relicensed. However, since the graphical user interface and the open-source, modified LimeWire core are run as separate processes, communicating via UNIX pipes, Acquisition's supporters argue that this usage is entirely permissible, as the GPL considers piped communication a valid method of separating programs in most cases. This follows in the footsteps of the precedent set by Apple's closed-source Xcode suite, which relies on open source components such as gcc and gdb.
