Home page: http://ols.lxtreme.nl Sources: https://github.com/jawi/ols This is a Java-based client for logic sniffers such as the open hardware "Open Logic Sniffer" (http://dangerousprototypes.com/open-logic-sniffer) and is the successor of the now defunct SUMP project, which currently resides in zugaina (http://gpo.zugaina.org/dev-embedded/sump-analyzer) and I believe is non-working at this time. My cursory review of the license seemed suspicious, since the original SUMP software is licensed under GPLv2 yet it claims to also be affected by the "OSGi Specification License, Version 1.0" (for using the OSGi specification), the Apache v2.0 (Apache Felix), and BSD licenses (JGoodies). Then again, I'm not sure how this pans out when considering the way that Java programs are legal considered to be "linked." Also, I didn't think that there was any legal ability for an organization to assert a license usage upon somebody for writing software that follows their specification, so the OSGi thing may just be fluff.
Ahh, at first I didn't understand why you changed my summary line, but now I see it. Yet another unfortunate aspect of this software, "what the f*** is the name!?" It resides at ols.lxtreme.nl, the tarball is named ols-0.9.7, the github page is github.com/jawi/ols but it isn't really "OLS", it's "Logic Sniffer." I'm guessing that it was forked from something called "OLS" and they never properly changed the name of the project? Even worse is that it appears that "OLS" was originally supposed to be an abbreviation for "Open Bench Logic Sniffer." Still, I have found it to be helpful, functional and useful enough to believe that it should have an ebuild. My only other comment is to propose that it should probably be classified under sci-electronics or some such (diagnostic tools or whatever).
