Notice when making the decisions/suggestions using Open Sources

Almost of you, IT guys have already read/heard/used some Open source libs.
In case we work with Japanese clients, specially with big clients, they are really sensitive about it.

Firstly, is it OK with the license type. Some clients are worrying if they have to public their name to Open source socials. This point leads their images down much?

Secondly, is it OK with current stability of that open source. They also check bug number reported, bug trend and also how many companies/clients are using it. Some clients forbid updating/modifying even that some new bugs are found.

Finally, you maybe are complaint if you didn't check and make sure the Open source has any troubles like going to law or not.

Offcourse, you should test/check and make sure that the suggesting Open source has no conflict with current frameworks, libs.

Hope you can have some points to check and consider before making your suggestions.
